Create a script called pyramid.m that plots a function Y(X) which is zero for X 0).*(X <1) or (X>0).*X.

Create a script called pyramid.m that plots a function Y(X) which is zero for X<-1, X+1 for -1<=X<0, -X+1 for 0<=X<1 and zero for X>=1. Plot it using 150 points and a range from -2 ... 2. Do not use a for loop.To do this create a vector X with the appropriate range and number of elements and compute the corresponding Y. To get an idea, try to plot (X>0) or (X>0).*(X<1) or (X>0).*X.
