Description:
------------
A change that would be interesting in the method transpose (line 661), is the possibility of if transposing not square matrices, with little change in the implementation of the method. Another suggestion is in the method "multiply" (line 1156), where it could receive a parameter from a scalar number to multiply for the entire matrix, it follows some examples

Test script:
---------------
Transpose a matrix non square:

function TransposeMatrix ( $m ) {
list($n_lin, $n_col) = $m->getSize();
$tmp = buildMatrix($n_col, $n_lin);
for( $i = 0 ; $i < $n_lin ; $i++)
for( $j = 0 ; $j < $n_col ; $j++)
$tmp->setElement( $j, $i, $m->getElement( $i, $j) );
return $tmp;
}

multiply by a scalar number, sorry, i don't see the method scale, disrespect this citation
