How much time will solve need?...

Maple
Hello Is there any possibility to check how long solve will need for a solution? I have to solve a littlebit complex equation set, so solve seems to need a little longer than usual. In my case I have tryed it for about 2 hours .. than I had to turn of my notebook. If it would be possible to check if solve would work for month, weeks, days or hours it would be a great help. us rene

solve a non-linear matrix equation...

Maple
Ich searched a lot but solve return me an error or just don't solve it. An the linsolve package is the wrong for that use How can I solve something like this with maple: A := Matrix(2, 2, {(1, 1) = a, (1, 2) = b, (2, 1) = c, (2, 2) = d}) E := Matrix(2, 2, {(1, 1) = 1, (1, 2) = 0, (2, 1) = 0, (2, 2) = 1}) solve((VectorCalculus[DotProduct])(A, A) = E) brings an error A korrekt solution would be for A for Example Matrix(2, 2, {(1, 1) = 0, (1, 2) = 1, (2, 1) = 1, (2, 2) = 0}) us rene
