Hi,
I have done a coding in matlab and this is the point where I am hanging,can anyone please help me out?
I have an equation
P(i,j)=Q(i,j)+R(i,j)/2;
Where P,Q,R are all matrices of dim=4x4.
Values of R(i,j) is given to us.
Now,initially assuming Q-matrix to be a zero matrix (all the elements are 0), the P(i,j) matrix is calculated. My, problem is that, once I calculate the P-matrix, I want to assign its value to the Q-matrix (a new Q-matrix instead of the initial zero matrix) to calculate a new P(i,j)-matrix. In this way I want to run the iterations for 4-times.
Will anyone please help me out over here?
Thanking You!

Please post the existing code and explain, which problems occur. To help you out, it is required to know the problem.

Last known code was completely non-functional: <http://www.mathworks.com/matlabcentral/answers/27367-matrix-iterative-solution-using-matlab>

Do you mean something like this:
Q = zeros(4, 4);
R = magic(4);
for k = 1:4
P = Q + R;
Q = P;
end
?
