VBA_orth checking for NaN values

[NicolasClairis]

It would be good to add a line to check for NaN values in the VBA_orth function Something like

if nonzeros( isnan(A) ) error('your matrix should not include any NaN value'); end

at the start of the script because otherwise any parasite NaN value will create a column full of NaN in the output possibly messing with other scripts afterwards.
