I am trying to check the results from an Eigen decomposition and I need to
force a scalar multiplication. The fundamental equation is: Ax = lx. Where 'l'
is the eigen value and x is the eigen vector corresponding to the eigenvalue.
'R' returns the eigenvalues as a vector (e <- eigen(A); e$values). So in order
to 'check' the result I would multiply the eigenvalues ('l') by the
eigenvectors. But unless I do it one by one (say e$values[1] * e$vectors[,1])
'R' tries a matrix multiplication and that is not what I want. I would like a
matrix that is formed by the SCALAR multiplication of each of the values by the
corresponding eigenvector. How can I force such a multiplication?
Thank you.
Kevin
