function [result] = multisvm(TrainingSet,Group_Train1,TestSet,Group_Test1)
%Models a given training set with a corresponding group vector and
%classifies a given test set using an SVM classifier according to a
%one vs. all relation.

what shows up for
which multisvm
I suspect that you are invoking a Mathworks function
