For help!How to express the following formula in CVX?

[XvanXvan]

In the following formula, k represents any integer in 1-4, m represents any integer other than k in 1-4, and n represents any integer in 1-240. In my opinion, the left is a three-dimensional matrix and the right is a two-dimensional matrix. How can I express that the left and right sides are equal?

How to vectorize most constraint loops in CVX

Using permute and repmat, most constraint loops in CVX can be eliminated. For example, the following: variables X(N) Y(M) Z(N); for n=1:N for m=1:M if n~=m && n^3>m^2 X(n)>=Y(m)+Z(n); % (1) end end end The first step is to expand. (1) actually means there are M*N constraints, so X is expanded to repmat(X,1,M), Y is expanded to repmat(Y,1,N), Z(n) is expanded to repmat(Z,1,M), according to their original dimensions. Now, repmat(X,1,M) is a N-by-M matrix, rep…
