Frobenius norm
Computes the Frobenius norm.
frobenius_norm(m)
m |
Data matrix with the residuals. This matrix has the same dimensions as the original data matrix. |
Residuals are vectors. If there are p variables (columns), for every observation there is a residual that there is a p-dimensional vector. If there are n observations, the residuals are an n times p matrix.
Real number.
