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

You have to change the order of your program.

d = 4567; % some value necessary
e = 1234; % some value necessary
f = 4567; % some value necessary
for a=1:10
 for b=1:10

    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;


   if  K==M
     print(a);
     print(b);
     print(d);
     print(e);
     print(f);

   end
 end
end

You not seem to have correctly understood the basic concept of a programming language. In a programming language (unlike mathematical notation) the statements are commands that are executed sequencially, one after another. All values that are needed in a computation have to be available when that command is executed, hence the updated execution order is necessary for intended operation.
