I think you mean rank, not range (both of these words often translate
to the same word in Spanish, although I prefer "contradominio" for the
range of the matrix as a function).

The numerical rank of a matrix is often computed via a singular value
decomposition. Compute the SVD, and then count the number of singular
values that are above machine epsilon. Have a look at
