linspace and arange

np.linspace(a, b, n) gives $n$ evenly spaced points from $a$ up to and including $b$ — both endpoints are included. np.arange(a, b, s) works like range, but returns an array and also accepts decimal steps.

\text{linspace}(a, b, n)

spacing between points:

(b-a)/(n-1)

Symbols

$a,\ b$	start and end value
$n$	number of points

Example

np.linspace(0, 1, 5) gives [0, 0.25, 0.5, 0.75, 1], spacing $1/4 = 0.25$ .

linspace takes the number of points, arange takes the step size — easy to mix up.
