%% Specify Interval of Mesh Plot and Plot Piecewise Input
% Plot the piecewise input
%  \matrix{{\rm erf}(x) + \cos(y) & -5 < x < 0 \cr \sin(x) + \cos(y) & 0 < x < 5}
% over the interval -5 < y < 5.
% Specify the plotting interval as the second argument of fmesh. When you plot multiple inputs over different intervals in the same axes, the axis limits adjust to include all the data.

fmesh(@(x,y) erf(x)+cos(y),[-5 0 -5 5])
hold on
fmesh(@(x,y) sin(x)+cos(y),[0 5 -5 5])
hold off
