thank you for this code, it great ; but i have an error when i try to change the kernel function. The error is " Error using ==> seqminopt>seqminoptImpl at 203
No convergence achieved within maximum number of iterations.
Error in ==> seqminopt at 84
[alphas offset] = seqminoptImpl(data, targetLabels, ...
Error in ==> svmtrain at 541
[alpha bias] = seqminopt(training, groupIndex, ...
Error in ==> multisvm at 49
svmStruct = svmtrain(T,newClass,'kernel_function','linear' ); %
I am using rbf kernel function, you must change it also
Error in ==> teststa at 61
[itrfin] = multisvm( data,classa,test )"
can you help me please?
is it possible to plot confusion matrix for this program... if so how to do tat.. we have tried many combinations but does not working...
else any method to calculate the performance of the overall system from test data's..
