Download Version 3.0 of this function and give suggestions for improving it. Version 3.0 includes the usage of multiple row testing matrix input.

@pallavi
Sorry for late reply, but I was little bit busy.
You can use '|' instead of '||' or '&' instead of '&&' in function,hope this will work for your application. You can refer Operators and Flow Control in Matlab for more information.
Thank You for taking help.

@Gomathi C,
Sorry for late reply, but I was little bit busy.
By the way you don't have to worry about using this function for two class SVM. You can not use this function for two classes, because their is an inbuilt MATLAB function for two classes classification present in MATLAB IDE. I created this function to extend the facilities of inbuilt MATLAB function.
I am not able to understand your output of GLCM but you can look image associated with my file in MATLAB file exchange for example of using my SVM function.
If you still find any problem in using your inputs for your program then please clarify me whole parameters you are using for GLCM like autoc, contr etc. So that I am able to tell you more clearly.
Hope this will help you.
Thanks for using my function.

@guo,
Hi, you correctly spotted the algorithm behind this file.
Now take an example,
Suppose
T=[1 2 3 4;2 3 4 5;3 4 5 6;4 5 6 7]
C=[1 2 3 4]
tst=[3 4 5 6]
then run the function and then debug it step by step to understand algorithm.
It becomes clearer how the class is calculated.
Thanks for your interest.

@Aziz,
Dear Aziz, svmclassify never makes 'classes' variable as a row vector of 0 and 1. The 'classes' can used only for checking loop condition i.e.,whether loop is to be terminate or not (check in while condition).
Variables 'newClass' and 'c1' can takes form of vector(0 and 1) and changing their sizes in each iteration.

I am using operands || and && because I am working on C Programming also so I am habitual of using this instead of logical scalar values.

May this solve out your confusions. Read Comments on file thoroughly. Thanks for taking help.
Regards...Anand Mishra.

hey ; why i can't see the file could you send it to me to( billelnet009@gmail.com )
please i really need it it's emergency

please i need to know it's one vs all or one vs one relation??

Hi
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?

sir,
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..

Hi

Could you please upload a test case for us to see how to use it?

Thnx.
