Hi Mark, what would be the easiest way to implement a legend/key? are there any examples which can be looked at without having to write alot of Java2d code?? ...
Hi, My suggestion would be to write it as a Swing component, and then add it to a layout manager along with the graph. A component something like (in ...
Does anyone know the algorithm used in the running median method, i.e. Turlach vs. Stuetzle or perhaps another method. I know, I know, I suppose I could get...
Let me know which it is, and I'll note it in the javadoc. public static double[] runningMedian(double[] v, int width) { if(v.length<width) throw new...
Hi, I'm working on the NetBeans integration of JSci. I'm not really sure how I could do the parsing right. My source is a InputSource and I need a way to...
Hi, I've committed to the CVS an updated MathMLParser class for you. I have added static translateXXX(Node node) methods. You can pass them the MathMLDocument ...

Hi everyone, i'm having hard times trying to get the JSci package to work. I've literally followed the instructions contained in the index.html file: 1-...

Ok, now that i solved some silly problem i really need your help. I've got a discrete signal stored in a 256 elements array. What i need is to compute its...
I was wondering why the method ____ Signal filter(double[] f) Apply the given array as a convolution Filter and return a new Signal. ____ does return a shorter...
It has to, otherwise the array index would go out of bounds: y(k) = \sum_{l=0}^m f(l) x(k-l) In the discrete case, signals only extend over a finite range....
... I've unsterstood the reason why it would go out of bound. Anyway I extended the original signal simmetrically (to avoid discontinuity problems) with a...
If you have a signal of 2N and filter of N, you should get an output of N+1. Is there any known standard/example signal that when convoluted with some...
In addition to what i just wrote, why does the resample method return me a distorted and noisy signal?!? Is there anything wrong with the java code or am i...
I've added a test case for resample() to the cvs. It looks like it works ok. ... ___________________________________________________________ To help you stay...
... And that is the correct size of the result? What if i want to compare it with the original signal? Should I resample it to 2N samples? Or that is not...
... Sorry I didn't understand where u added the test case to... Anyway if u look at the images i posted u can see that the two signal are quite different. The...
Ahhh, I tested EngineerMath.resample(), not signal.resample(). Are you doing out=signal.resample().evaluate()? Because that would involve Cascades and that...
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...
