In writing codes how can we reduce the CPU comutation time spent for e.g. finding a large Determinant of order 15*15(or even more) of 2 or 3parameters.puting it to zero and solving it for one of the parameters? suppose I have a Matrix of 3 parameters(a,b,c) named M, with(LinearAlgebra): N:=Determinant(M); solve(N=0,a); Here what shall I do for reducing the CPU spent time?
