Creates the perspective transform of a scalar convex or concave expression.
Given a scalar expression f(x) and a nonneg variable s,
the perspective is s * f(x/s).
Usage
perspective(f, s, f_recession = NULL)
Arguments
- f
A scalar convex or concave Expression.
- s
A nonneg Variable (scalar).
- f_recession
Optional recession function for handling s = 0.
Value
A Perspective expression.
