>> help linspace
 linspace Linearly spaced vector.
    linspace(X1, X2) generates a row vector of 100 linearly
    equally spaced points between X1 and X2.
 
    linspace(X1, X2, N) generates N points between X1 and X2.
    For N = 1, linspace returns X2.
 
    Class support for inputs X1,X2:
       float: double, single
 
    See also logspace, colon.
