Dear Scott, jpmay,
Neither _EnvAllSolutions:=true nor AllSolutions in the line have a desired effect on the result.
I have a large matrix of omega, k1, k2 named M. I want to evaluate its Determinant and solve it for omega. Then I want to plot the real solutions of omega versus k1 or k2 or k1=k2=k in a range (0..0.5).
For this purpose, I've written the codes as follows: [I'm a M.Sc student in physics and almost a newcomer in Maple.]
M:=Matrix(num,num,g); #here num=7
local H, sol, p, z;
global N, ω;
H:=evalf(subs(k1=x, k2=y, N));
if type(x,symbol) then z:=x; else z:=y; fi;
L(k,0), L(0.5,k), L(k,k) will give me the desired results but when the matrix becomes larger, the computation time grows very much.
Concerning real solutions, I just wanted to know that besides using RealDomain package, is there any other simple and accurate way for obtaining those and also I should decrease the computation time if possible.
I will be glad if one could help me on this subject.
Thanks a lot
