Hi, I'm trying to use the luDecompose method of DoubleSquareMatrix, and am not getting the correct answer to my test problems. I'm hardly a master of LU...
Hi, luDecompose performs the LU decomposition up to a permutation given by the pivot array. That is, the original matrix M is permutated to a matrix M' and...
Hi Mark, I'm always impressed with your quick responses. Unfortunately, I'm one of those people who hit the math wall at long division, and have no idea what ...
Yes, it does. The LU decomposition is often an intermediary step, so the fact that it is permutated (scrambled) usually doesn't matter because you either...
Hi Mark, If it isn't too much trouble, adding the textbook version of LU decomposition to JSci would be helpful. Part of the reason for my editor is as a...
Hi Mark, Seems to work! Thanks. Steve Sinai ... === message truncated === __________________________________________________ Do You Yahoo!? Tired of spam?...
Does JSci have any any kind of linear regression-solving capabilities? I searched through, but couldn't find anything. It's no big deal if it doesn't, as I...
Hi Mark, I found it. Thanks, Steve ... __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam...
I had some problems getting the inverse Fourier Transform to work. I have a Fourier Amplitude Spectrum (FAS) that with increasing positive frequencies, the...
Hi, As the data is increasing positive, increasing negative then you don't need the first initial sort, ie inverseTransform(data), if you want the output in...
Hello, So I found out the issue. Matlab uses -2pi in the transform and 2pi in the inverse, whereas JSci uses 2pi in the transform and -2pi in the inverse...
OK, thanks, I will make a note in the javadocs. ... From: alkottke <alkottke@...> To: jsci@yahoogroups.com Sent: Friday, 25 August, 2006 5:23:42 PM ...
Every square matrix should have its determinant. However, when I use the det() method in class DoubleSquareMatrix, I sometimes get NaN. For instance, if I ask...
Hi; let me first thank you for this great piece of software, I'm enjoing testing its possibilities and learning some Java in the course. Being new at Java this...
Hi: I am interested in sending mathml to Matlab through Java and solving the equations. But matlab inherently doesn't understand Mathml. I have come across the...
Hi: I have my mathinfo of PDEs(Partial Differential Equations) and ODEs(Ordinary Differential Equations) in mathml. Can this be parsed using the existing Jsci...
Hi, The mathml DOM implementation in JSci, I believe, can parse them. That is you can access them from the DOM tree. But the high-level JSci object parser...
Hi, The MathMLParser can translate MathML into Java JSci objects or code, i.e. <cn>45</cn> ---> new MathDouble(45) There is some information in the jsci...
Hi, jsci-mathmlimpl is an implementation of the DOM MathML API. There is also a higher level JSci.io.MathMLParser which converts the DOM API directly into JSci...
Hi!
Thank you for your answer. I read this document. If the translation is
successful is there any chance to get the type of the elements without
testing with...
Hi Herbert: As far as I understand, this(mathml) is just the representation of the (math)information. There is no solver attached to it. You have to send this...
hi Mark: Are there any examples available for this implementation? (Mathml to JSci Objects)?? I didn't find any such example in JSci package. Thanks Pavan ... ...

Hi: I am not sure if evaluate( )-mathod will do non-numeric evaluations. I see that your mathml is non-numeric in nature (I mean symbolic). This is the output...
