How to set Sigma value in CompactClassificationSVM in Matlab

Hi;

I'm new to Matlab and I would like to set the value of Sigma for the class CompactClassificationSVM

I couldn't find away to set it's value. I tried for example;

CompactSVMModel.Sigma

But I got the error message:

Error using subsref
No appropriate method, property, or field 'Sigma' for class 'ClassificationECOC'.

Any clue?

Binary SVM models trained by ECOC are saved in the BinaryLearners property, which is a cell array. You can't change the Sigma property (it's not writable), but you can see what it is for all learners.
