Does anyone have a good algorithm for the calculation of cumulative
Levy distributions other than Cauchy, normal and alpha = 1/2 cases?

hello friends

i'm a mechanical engineer. i have to prepare an interface for an engineering
project using with Visual Fortran programming language.

i have learned something about Visual Fortran but i need your help to improve
myself and i have problems about the writing of modules, windows applications.

Can you help me

Waiting for your messages.

Thank you that works also, I used ACOS(-1) but that adds another variation =)

I am very new to FORTRAN and need to learn it quick. I wrote the
following code to find the definite integral of x^2 between 0 and 1
which should come out to 0.33333 etc. This same code with slight
syntax changes works in visual basic. When I run it in FORTRAN I
get .015625

The strange thing is if I try to make it less accurate by setting
dxval to 1000 and running the DO loop 1000 times I get a much more
accurate answer of .332828, running the same code in VB 1000 times
gives me .332833

I am guessing this has to do with a lack of understanding on my part
of how numbers are stored and calculated in FORTRAN variables but I
just can't find the mistake. I also tried converting dxval in the DO
loop to an integer with int(dxval) and still got the same result.

Here's the code. I am using a compiler called Plato3 and running it
under Windows XP.

PROGRAM  ERIC
IMPLICIT NONE

real,parameter :: dxval=100000000.0,lower=0.0,upper=1.0
real :: dx,x,y
integer :: i

y=0.0
dx=(upper-lower)/dxval
x=0.0

DO i = 1,dxval, 1
    y = y + ((x**2)*dx)
    x = x + dx

END DO

write(*,*) y


END PROGRAM

ty works as ACOS(-1) Did more research when I was less frustrated =)

Hi,

  Try:

  PI = ACOS(-1)

Hint: Look at the definitions of ACOS, ATAN, and/or ATAN2.

PI = ATAN(1.0)*4

Hello,

I got a copy of Fortran Power Station from 1994.  I love it.  I have
alot of algorithms for doing just about everything.  I have been
looking for the IMSL libraries for Fortran 77, but I can't find them.
  Maybe somebody in the group could help me.  I program mathematical
algorithms for engineering and science applications.  I program in C,
C++, Java and Fortran.  I even got an old computer to run the Fortran
compiler. It is so simple.  Don't get me wrong I program C++ in a high
power computer.  But I refused to let to waist all of my algorithms in
Fortran 77.

Thanks for the help.

Hello,

Does anyone know how to read data from a Matlab-generated binary file
into Fortran code?

Thanks,
Juan

I think Process Explorer is probably better than winxp's Task
Manager. Otherwise, just a guess, whilst running, try the "mem"
command from a Dos_prompt.

Hi all,
I am new to fortran, so I am just trying to know how fortran code
uses memory.
I run a fortran program and want to look up how much memory it uses
while its running. I look at the task manager(windows XP) to know
the memory usage.
I am using the following code to know how much memory my arrays are
using:
>>>>
allocate(a(nx))
............
............
............
.............using a() here..........
..........
.........

pause -----[1]

dealocate(a)
pause-----[2]

>>>>>>>>>>

I check the task manager at [1] and [2].
When I ran the code with multiple arrays (instead of just one), I
didn't see any significant change in memory at [1] and [2] pause
statement. I am just wondering if there is any other program which
can tell me 'not so significant' memory changes?

Thanks.

How do you model a RS flip flop in matlab?

In 1974, Gustav Larsson, a young programmer from Helsinki,
Finland, stumbled upon an amazing discovery. While working
with a PDP-8 mainframe computer, Gustav suddenly because
bored. He decided to attempt to compile a single byte
program. For what reasons we cannot know.

Nevertheless, Gustav was already familiar with RTPS FORTRAN
and thus picked a single character to represent the
contents of the program: "@". Once compiled, he expected
nothing to happen.

He was wrong. To his absolute amazement, it compiled
successfully!

Using an ARS-33 Teletype, Gustav printed out the 1 byte program
followed by its output. It appeared to contain a message from
God. A devout Catholic, Gustav showed it to his immediate
supervisor, who ordered both the print out and the program
itself destroyed. Although Gustav complied with his wishes,
it is rumored that he kept a copy of the printout in a small
shoe box in his apartment in Helsinki.

He also kept a brown diary which included various small
passages from the "Helsinki Code" (as he described it years
later). According to Gustav, the Helsinki Code came directly
from the 'Mind of God.'

The Helsinki Code read (in part):

"...[M]y presence in your world is unalterable for I am the
sanctuary of both the cosmos and the one soul inside you. I
could awaken each of you in this very moment to [my] unity,
but there is a larger design - a more comprehensive vision -
that places you in the boundaries of time and the spatial
dimensions of separateness...[T]he design requires a
progression into my wholeness that reacquaints you with
[my] unity through the experience of separation. Your
awakening, while slow and sometimes painful, is assured,
and this you must trust above all else..."

(Page 26 of Gustav's Journal - Dated February 10th, 1975)

Gustav passed away in 1996. Although his diary has since
turned up missing, the above fragment from the 'Helsinki
Code' remains. Perhaps, just perhaps, we can learn to
be better people simply by reading it.

Hello all,
I am hoping you will help with a Fortran Language
Dictionary (cheat-sheet) page in the Software
Engineers' Handbook Wikibook. I'm looking for a quick
overview of general program structure with pointers to
more specific information. (Yes, I could look this all
up, but it's much much faster if you know the language
well and have used it recently. The site is under the
GNU Documentation License, so I don't want to take
examples directly from books and many online
references.)

Here's the Fortran page:
http://en.wikibooks.org/wiki/Software_Engineers_Handbook:Language_Dictionary:FOR\
TRAN

Here is the web site for the wikibook
http://en.wikibooks.org/wiki/Software_Engineers_Handbook
I would love help with the other pages too.

I would be happy to coordinate submissions for folks
unwilling to adjust to wiki markup.

Thanks for the help!
Chris

F90 pointers are funny creatures in that almost any reference to them
causes them to be dereferenced.

The "usual trick" with F90 pointers is to place them into a derived
type:

	 type rpointer
	   real, pointer :: p(:) => NULL ()
	 end type
	 :
	 type(rpointer) :: my_pointer
	 :
	 print '(a,z)', 'the address of my_pointer is: ', loc (my_pointer)

This is also the "usual trick" for defining arrays of pointers.

HTH,

Walt

F90 pointers are funny creatures in that they are dereferenced in
almost all contexts.  You are not supposed to be able to get at them
directly.

A "usual trick" with F90 pointers is to place them into a derived
type:

         type rpointer
           real, pointer :: p(:) => NULL ()
         end type
         :
         type(rpointer) :: my_pointer
         :
         print '(a,z)', 'the address of my_pointer is: ', loc (my_pointer)

This is also the "usual trick" for defining arrays of pointers.

There are two problems with the example code, but these are
probably only the tip of the iceberg.

i.    The $ format descriptor means write the line without a newline
       (Carriage return, linefeed etc) at the end.  It is non-
       standard, but is supported by most Fortran systems.  Most (not
       all) of those do not require a comma to separate the $ from
       the next token. Your Solaris compiler either doesn;t accept $
       (there is an alternative and standard mechanism in Fortran 90)
       or requires the comma.

ii.    The Fortran standard requires that a COMMON block (except the
        un-named common) is the same size wherever it is referenced.
        Many Fortran compilers do not impose this restriction.  Most
        Unix compilers do.  Yours does.

The underlying problem is that the code was written for a fairly
permissive system like VMS or CVF, and won't run on a strict Fortran
90 or Fortran 77 system.  We have a tool, WinFPT (See
http://www.simcon.uk.com) which will convert the code.  Please
contact us if you would like to use it.

Best wishes, and good luck!

John.
