What's the first " * " doing?

svmStruct=*svmtrain*(trnData,grp,'showplot',true);

Thanks for your reply.

I think "*" was put by mistake. I am still getting same error which i mentioned in my earlier comment.

Can you please suggest how can i resolve this.

P.S - I removed "*" from my code.

Thank You, Gaurav N.

svmtrain was available only in Bioinformatics Toolbox until R2012b. It came into Statistics Toolbox in R2013a. So the question is, do you have the appropriate toolbox?

Enter the command

ver

at the MATLAB command line, and see whether you have it.

Thank You Alan for your reply.

I am using below Matlab version as checked using "ver" command and looks like Bioinformatics toolbox is not available in the list of given toolbox.

MATLAB Version 7.11.0.584 (R2010b)

Can you please suggest how can i get this Bioinformatics toolbox on my current version of matlab in order to get svmtrain?

Thank You, Gaurav N.

Please contact sales to purchase an appropriate license. You might prefer getting an update to R2013a with Statistics Toolbox rather than upgrading your R2010b version to Bioinformatics.
