Matlab doesn't store sparse matrices as JxJ arrays but as lists of size O(J). See http://au.mathworks.com/help/matlab/math/constructing-sparse-matrices.html Since you are using the spdiags function to construct A, Matlab should already recognize A as sparse and you should indeed see such a list if you display A in console view. For a...

Selecting a few lines that are causing misbehavior. TI=0; TF=1; sigma=2; dx=0.01; dt=(dx^2)/(5*sigma); // .01^2 == .0001, 5*sigma == 10, dt := .00001 timesteps=(TF-TI)/dt; // TF-TI == 1, 1/.00001 == 10000, timesteps := 10000 timesteps=int8(timesteps); An out-of-range condition occurs in that final line. MATLAB clips overflows in type casts to...

You have to start Eclipse with the -debug option to turn this on. You can also specify -debug filename to specify a different path for the options file...

For some reason (which are not completely clear to me) the pdeplot function internally calls hold off. So, to get the desired result you need to add a hold on after each call to pdeplot....

Well got the answer to my question. In my feature.xml file , I added GMF runtime and tooling as dependancies. Hence during installation , Eclipse takes care of installing the required plugins i.e GMF runtime and tooling for the proper functioning of my plugin....
