Principal Component Analysis using Function

Hello All,

I have a PCA.m function I want to use it on a set of datapoints for computing the PCA. So I write the following line but it doesnt seem to return anything (NaN)

        my_pca = pca(datapoints,1);

where pca is my pca.m

Am I doing anything wrong here or is there a simpler way to do it? Thanks, \ksnf3000
