x = -10:0.1:10;
f1 = trapmf(x,[-2 0 0 2]);
if i plot(x,f1), this will give me a triangular wave.
I need to seperate the f1 values into two sections, one left of the peak and one right of the peak.
any help would be appreciated.

x = -10:0.1:10;
f1 = trapmf(x,[-2 0 0 2]);
[a,ix]=max(f1)
x1=x(1:ix-1)
y1=f1(1:ix-1)
x2=x(ix+1:end)
y2=f1(ix+1:end)
plot(x1,y1,x2,y2)
