loop and mixing solution

Variables A, B, C each varies from 0 to 100, and their sum equal to 100.

How should I do it?

I was trying to run this:

for A, B, C = 0:10:100, A+B+C=100,

z=A*0.1+B*0.2+C*0.3

end

It did not work. Apparently.

A = 0:10:100 ; 
B = A ; 
C = A ; 
[A,B,C] = meshgrid(A,B,C) ; 
% convert them to columns 
A = A(:) ; B = B(:) ; C = C(:) ; 
% get the sum 
thesum = A(:)+B(:)+C(:) ; 
% get the indices whos sum isequal to 100 
idx = thesum==100 ; 
% pick the values 
A = A(idx) ; B = B(idx) ; C = C(idx) ; 
% ge the required Z
Z = 0.1*A+0.2*B+0.3*C ;

Thank you. That works!

One more question, if I need to get z from a few tables, can I do the following?

If Variables A, B, C each varies from 0 to 100, and their sum equal to 100.

for A, B, C = 0:10:100, A+B+C=100,

z=A*T1.+B*T2.+C*T3.

end

T1, T2, T3 are tables, containing similar structures (same columns/rows, similar type of data)
