FIT function does not work in parfor
I have a 4D data set D[nX, nY, nZ, nT]. I need to fit a curve to the elements of this data. Currently this is how I do it - for x = 1: nX for y = 1:nY for z = 1:nZ T(:) = D(x, y, z, :); if T(0) ~= 0 [cval err] = fit(time, T, fitFunction, options, 'problem', delT); cval = coeffvalues(cf);... 19 May 2010 10:26

Constrained neural network
Hi all, I am training a network using the 'newff' function. The output so far is good but for one issue. The y-axis of the output represent percentage (max=100) while the x-axis represent some other variable. The problem is that the output of the algorithm sometimes gets to 120% which is not possible with the type o... 20 May 2010 08:21

fopen doesn't always open
I use MATLAB 2007 R14. I have two similar text files, both of which contain information about trusses - number of nodes, nodal coordinates, number of truss elements, element connections and constraints, and applied forces. When I input the one document, using fid=fopen(filename,'r'), everything is fine, but the othe... 19 May 2010 09:19

Galil Motion Controller
Hi! I am working on RIO 47200 Motion Controller for antenna steering. I have developed an interface in Matlab to access the C code written in Mex file format for antenna steering. I can compile the Mex file in Matlab for the first time and the program runs fine. If i recompile the program then it crashes the Mat... 19 May 2010 09:19
