Varying constant in Matrix calculation to generate 3D plot

I'd like to generate 3D plot where x,y,z (= a,b,answer) while I am varying a (0 a = 0.2(*constants*); b = 0.5(*constants*); matrix = RandomReal[{-1, 1}, {4, 2}]; matrix1 = matrix[[All, 1]]; matrix2 = … matrix[[All, 2]]; inter1 = a/b matrix1; inter2 = 1/b matrix2; inter = inter1 + inter2; answer = Total[inter] …
