I have noticed that,
for :
x = Matrix( 1, 10 , 1 );
// returns matrix:
z = 10 ^ x;
// returns array:
z = log( x ); //
error:
x = Matrix( 10, 10 , 1 );
z = log( x );
Just in case someone would need to calculate the log() of all the elements in a matrix, the following function will do that.
function mxlog( mx )
{
m = MxGetSize( mx, 0 );
n = MxGetSize( mx, 1 );
for( j = 0 ; j < n ; j ++ )
{
block = MxGetBlock( mx, 0, m - 1, j, j , True );
mx = MxSetBlock( mx, 0, m - 1, j, j , log( block )
}
return mx ;
}
