You mean, how to plot the triangle? You can do,
x=linspace(0,3,1000);
y=(1-abs(x-1));
y=y.*(y>=0);
plot(x,y)
A somewhat more analytic representation —
x = linspace(-1, 3, 250);
y = (x).*((x >= 0) & (x < 1)) + (2-x).*((x >= 1) & (x < 2));
figure
plot(x, y)
grid
ylim([0 2])
This can then be separated into its component parts, if necessary —
y1 = (x).*((x >= 0) & (x < 1));
y2 = (2-x).*((x >= 1) & (x < 2));
.
