What are you trying to do?
Disciplined convex programming information:
log(X) is concave and nondecreasing in X. When used in CVX
expressions, X must be concave.
Disciplined geometric programming information: log(X) is typically not used in geometric programs. Technically it possible to do so in certain advanced cases, because monomials and posynomials are treated by CVX as log-affine and log-convex constructs, respectively. However, such usage is undocumented and will not be officially supported.
