getting error 'Too many output arguments.'while running [coeff,score,latent,tsquared,explained] = pca(X2); WHY so ? whats the solution. I want to calculate cumulative variance with respect to PCs.

[Walter Roberson]

Which MATLAB release are you using? What is class(X2) ? What is size(X2) ? What shows up for

which pca(X2)

Thanks your question (which pca)solved my problem.

Make sure you don't have a pca.m file in your path, such as prtools, that is overriding the built-in pca function.

Answer 2

[Berkay TOPALOGLU]

i am getting the same error. How did you solve it?

I tried matlab's own instance and still get the same error.

load hald

[coeff,score,latent,tsquared] = pca(ingredients,'NumComponents',2);

Error using pca
