Dear all! I have the following problem. I have 4 values A,B,C,D each value has the size [3 x 1000]. A need to built matrix [A B; C D], which M [A(m,n) B(m,n); C(m,n) d(m,n)]. How to do it? NOw I have only the last result the code I have now :
if true
freq_points= 1000;
n = 3;
A = zeros(n,freq_points);
B = zeros(n,freq_points);
C = zeros(n,freq_points);
D = zeros(n,freq_points);
B = ones (n, freq_points);
for r =1:3
for la = 1:1:freq_points;
A(r,:) = exp(gamma(r,:).*d(r));
B(r,:) = 1;
C(r,:) = exp((-gamma(r,:)).*d(r))*(1/Z(r));
D(r,:) = -1/Z(r);
M = [A(r,la) B(r,la); C(r,la) D(r,la) ]
end;
end

First format your code so we can read it...keep at it until it looks right in the preview window.

Highlight your code and then click the {}Code button. See this: http://www.mathworks.com/matlabcentral/answers/13205-tutorial-how-to-format-your-question-with-markup

Take M outside the loop and do
M = [A B; C D];
So M is only created after A, B, C, and D have finished being created.
