inequalityplot

Plot inequalities in 2-D space.

inequalityplot(f,x,y,color,resolution) plots the inequality f(x,y) in region x(1) <= x <= x(2) and y(1) <= y <= y(2) using specified color. For multiple inequalities, use & in f. Default color is [0.5,0.75,1]. Default resolution is 400.

Example 1: A colored ellipse.

  ellipse = @(x,y) x.^2/4+y.^2<=1;
  inequalityplot(ellipse,[-3,3],[-3,3])

Example 2: A colored triangle.

  triangle = @(x,y) x>0 & x<1 & y>0 & y<x;
  inequalityplot(triangle,[-1,2],[-1,2],'magenta')

Example 3: Area under a Gaussian curve.

  g = @(x) 1/sqrt(2*pi)*exp(-x.^2/2);
  inequalityplot(@(x,y) y<g(x) & y>0 & x>-2 & x<1,[-3,3],[0,0.5],'c')
  hold on; fplot(g,[-3,3],'LineWidth',1); hold off
