plq_pa — Piecewise linear quadratic (plq), convex proximal average via conjugates
pa = plq_pa(f1,f2,lambda_pa)
matrix. A plq function with dimensions n x 4.
matrix. A plq function with dimensions n x 4.
constant. An intermediate function.
matrix. A plq function with dimensions n x 4.
Compute the proximal average (PA) of two plq functions at a specified lambda_pa value. The PA is computed using the following formula, where * represents the Fenchel Conjugate.
P(f1,lambda,f2) = [ (1 - lambda)(f1 + (1/2)||.||^2)* + lambda(f2 + (1/2)||.||^2)* ]* - (1/2)||.||^2
