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!

Accepted answer

Do you mean something like this:

Q = zeros(4, 4); R = magic(4);

for k = 1:4 P = Q + R; Q = P; end

?

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