multisvm T value error

function [itr] = multisvm(T,C,testselectfea)

u=unique(C);

N=length(u);

c4=[];

c3=[];

j=1;

k=1;

if(N>2)

itr=1;

result=0;

cond=max(C)-min(C);

while((result~=1)&&(itr<=length(u))&& size(C,2)>1 && cond>0)

c1=(C==u(itr));

newClass=c1;

SVMModel = fitcsvm(T,newClass,'Kernel_Function','rbf','Method','QP');

result = predict(SVMModel,testselectfea);

for i=1:size(newClass,2)

if newClass(1,i)==0

c3(k,:)=T(i,:);

k=k+1;

end

end

T=c3;

c3=[];

k=1;

% This is the loop for reduction of group

for i=1:size(newClass,2)

if newClass(1,i)==0

c4(1,j)=C(1,i);

j=j+1;

end

end

C=c4;

c4=[];

j=1;

cond=max(C)-min(C);

if result~=1

itr=itr+1;

end

end

end

end

what value should i assign to T

I' m trying to do it for brain tumor

any solution urgent assist plz

error

>> multisvm(T, C, tst)
