y = linspace(x1,x2)
y = linspace(x1,x2,n)
linspace generates linearly spaced vectors. It is similar to the colon operator ":", but gives direct control over the number of points.
y = linspace(x1,x2) generates a vector y of 100 points linearly spaced between x1 and x2.
linspace(x1,x2,n) generates n points.
