<br>Hi Achille,<br><br>Do you need the square root in the Matrix sense ?<br><br>Like, for Matrix M do you need the matrix Q such that:<br><br> M = Q * Q<br><br>or do you need it in the matrix-element sense where
<br>every element of Q is the square root of the equivalent<br>element of M, like:<br><br><br> Q[i][j] = sqrt( M[i][j] )<br><br><br>Please let us know,<br><br><br> Thanks<br><br><br> Luis<br><br><br>------------------------------------------------------------------------------
