plq_plot2 - Piecewise linear quadratic (plq), plot multiple functions

Calling Sequence

plq_plot2(x1, x5, f1, ..., fN)

Parameters

• x1 : number, optional. The lower x bound of the grid on which the functions are plotted.
• x5 : number, optional. The upper x bound of the grid on which the functions are plotted.
• f1 ... fN : matrix. The plq functions to plot.

Description

Plots a number of PLQ functions computed over the interval [x1,x5]. If x1 or x5 are not provided, or are -%inf and %inf respectively, then they default to -5 and 5.

Examples

f1 = [-1,0,-1,-1;0,0,1,1;1,0,-1,1;%inf,0,1,-1];  // The function abs(abs(x) - 1)
f2 = [-1,-3,-12,-9;1,4,0,-4;%inf,-3,12,-9];      // An "m"
f3 = [0,-3,-18,-29;3,0,-2,-30;%inf,0,40,-156];   // Another function
clf();
plq_plot2(-4, 4, f1, f2, f3);
