What is wrong with this MATLAB code?

Question

I am trying to do following in MATLAB,

global a b c d e f g h l;
A=[1 3;3 2];
B=[a 0;0 b];
C=[d 0;e f];
Ctranspose=transpose(C);
D=[sqrt(d) 0;0 sqrt(f)];
E=C         


        

Answer 1

In addition to everything mentioned here, please do format the code nicely (note: the code below is the OP's code, so it's programmatically wrong):

global a b c d e f g h l;
A = [1 3; 3 2];
B = [a 0; 0 b];
C = [d 0; e f];
Ctranspose = transpose(C);
D = [sqrt(d) 0; 0 sqrt(f)];
E = Ctranspose / D;
Etranspose = transpose(E);
K = A + E;
M = E * D * Etranspose;

for a = 1:10
    for b = 1:10
        if  K == M
            print(a);
            print(b);
            print(d);
            print(e);
            print(f);
        end
    end
end

This spares you time and mental resources when reading your code, which actually takes much more time than writing it.
