Dear All, is it possible to solve with fsolve an equation with 5 parameters using matrices instead of 5 for loops iterating on every combination of these 5 parameters?

No, it is not.

You can reduce the number of explicit for loops:

[G{1:5}] = ndgrid(Values1, Values2, Values3, Values4, Values5);
results  = arrayfun(@(g1,g2,g3,g4,g5) fsolve(... some appropriate arguments...), G{1}, G{2}, G{3}, G{4}, G{5});
