If loop inside the cvx

1

How to use if loop inside the cvx, is that is similar to without cvx or any thing changes??

Actually, if I use if loop inside the cvx, then I am getting below error in matlab:

In > (line 21)
In Paper_3_b_paper_7_Fig9_Code (line 181)
Error using cvxprob/newcnstr
Disciplined convex programming error:
Invalid constraint: {concave} > {invalid}

Error in > (line 22)
b = newcnstr( evalin( ‘caller’, ‘cvx_problem’, ‘’ ), x, y, ‘>’ );

Error in Paper_3_b_paper_7_Fig9_Code (line 181)
if permutation_wsr > max_wsr

But, without if loop, the full code is working fine, that’s why

CVX variables and expressions are not allowed in the condition on which if branches. I.e., something can’t be a CVX variable or expression in if something, .... end

You will need logic constraints involving Big M. Read up on this at Posts containing 'logic constraints' - Operations Research Stack Exchange .
