The part that makes sense for me is:
ans =
cvx log-convex expression (1x2 vector)
ans =
cvx log-convex expression (scalar)
ans =
cvx empty expression (1x0 vector)
The part which doesn’t is:
ans =
cvx positive constant expression (scalar)
and:
value1(2) == 1
ans =
1
since when u = 2, c is an empty matrix as obvious even in the command window how is the product of value(2,emptyMatrix) = 1 ?!
