Piecewise linear quadratic (plq), Minimum function
[plqm, minf] = plq_min(plqf, plqg)
matrix. One of the plq functions to compute the minimum of.
matrix. The other plq function to compte the minimum of.
matrix. A plq function equal to the minimum of plqf and plqg.
matrix. Specifies the intervals over which each function was the minimum.
Creates a plq function representing the minimum of plqf and plqg for all x values. This function runs in O(m+n) time and returns a plq function containing O(m+n) pieces, where m and n are the number of pieces in plqf and plqg, respectively.
plqf = [-1,0,-1,-1;%inf,0,1,1]; plqg = [1,0,-1,1;%inf,0,1,-1]; plqm = plq_min(plqf, plqg), clf(); plq_plotMultiple(-4, 4, plqf, plqg, plqm); plqf = [%inf,1,0,0]; plqg = [0,0,-3,-1;%inf,0,3,-1]; plqm = plq_min(plqf, plqg), clf(); plq_plotMultiple(-4, 4, plqf, plqg, plqm); | ![]() | ![]() |
