WebApr 20, 2024 · When X is a CVX variable, a a piecewise quadratic *approximation* is employed instead. This approximation gives good results when -4 <= x <= 4, and will be improved in future releases of CVX. For array values of X, the log_normcdf returns an array of identical size with the calculation applied independently to each element. X must be real.

If X is a matrix, quad_over_lin(X,Y) is a row vector containing the values of quad_over_lin applied to each column. If X is an N-D array, the operation is applied to the first non-singleton dimension of X. quad_over_lin(X,Y,DIM) takes the sum along the dimension DIM of X.

WebMay 1, 2015 · You can use the CVX function inv_pos(x), defined as 1/x for x&gt;0 and ∞ otherwise, for the convex portion of 1/x; CVX recognizes this function as convex and nonincreasing. In CVX, you can express the concave portion of 1/x, where x is negative, using -inv_pos(-x), which will be correctly recognized as concave and nonincreasing.
