Description

La solución del sistema S*L'=B da errores con TrSolve

Matrix L = Diag(3, 1);

Matrix B = Rand(2, 3, 0, 1);

Matrix S = TrSolve(L, B, 0, 1, 1);

Set View([[S-B]], "");

genera la siguiente traza:

<W>
Warning: [1] Cannot apply TrSolve to matrices T(3x3) B(2x3) </W>
<W>
Warning: [2] <W>Wrong sizes when trying to subtract two matrices (0,0) and (2,3).</W>
