here is my code
data=xlsread('cloln.xlsx');
B=data-repmat(mean(data),62,1);
[coff,score,latent]=princomp(B);
S=cumsum(latent)./sum(latent);
s=S';
display(size(coff));
for i=1:4
if(s(i)<0.99)
coff(:,i)=[];
end
end
display(size(coff));
score1=B*coff;

The PRINCOMP function calls PCA. Normally it calls the PCA function in Statistics and Machine Learning Toolbox but since you have created your own pca.m script file (C:\Users\user\Desktop\lib svm\pca.m) in the current directory or higher on the MATLAB search path than the toolbox, it tries to call that script file like a function instead. This will not work, and MATLAB throws an error when it tries to call that script like a function. I recommend renaming or removing your pca.m script file.
