Hello all, I want to plot variation of function P(x) over range of x from -10 till 20 where P(x) is defined as P(x)= 0 if x<=0; =x if 0<=x<=1; =2-x if 1<=x<=2; =0 for x>2;

for this I have written following code: clear; dx=0.5; x=-10:dx:20; function z = bilinear(x) if x>=2 z=0; elseif 2>x>=1 z=2-x; elseif 1>x>=0 z=x; else z=0; end fp=bilinear(x); plot(x,fp);

and matlab is giving me following error: ??? Error: File: Q2.m Line: 3 Column: 1 Function definitions are not permitted in this context.

Can somebody please help me to debug this,

Thanks in advance,

Nikhil
