How to replace 2×2 zero submatrix of B with 2×2 matrices different matrice.I have 12 matrices of size 2×2 and want to replace zeros of B by those matrices.

B =

0.8776 0.6513 0 0 0 0 0 0

0.0144 0.8646 0 0 0 0 0 0

0 0 0.2943 0.0560 0 0 0 0

basically i want solution in this form

x p1 p2 p3

p1 x p2 p3

p1 p2 x p3

p1 p2 p3 x

C={zeros(2), p1,p2,p3};
result=B+cell2mat( C(toeplitz(1:4))  );

MATLAB: Plot a the own created function

Your output is sometimes complex. You should fix this in your function, but you can also apply a quick fix here:

fplot(@(Lambda)abs(Steady_State(Lambda)))
ylim([0 200])

Ideally you should also make your function support vectorized inputs and deal with all the warnings (and suppress outputs by adding semicolons).

for P1 = 0 : .1 : 1
  for P2 = 0 : .1 : 1-P1
    P3 = 1 - P1 - P2;
      .... do whatever ...
  end
end
