Hi everyone, I would like to know if there is a command to form factor models and get the orthogonal matrix in matlab. For instance, let QAQ = covariance matrix of x and A is a diagonal matrix of eigenvalues of the matrix cov(x) and Q is an orthogonal matrix whose columns are standardized eigenvectors. How can I get the Q...the orthogonal matrix in matlab?
Thank you,
