The `values` sequence can either be another ~ulab.array, sequence of numbers

subsequence has the same length (in which case a 2-dimensional array is
created).
Passing a ~ulab.array and a different dtype can be used to convert an array
from one dtype to another.
In many cases, it is more convenient to create an array from a function
like `zeros` or `linspace`.

elements of the array. If both arguments are arrays, their sizes must match.

Multiplies corresponding elements of the two arrays, or multiplies
all elements of the array by a number. If both arguments are arrays,
their sizes must match.

The array is modified in place.
:mod:`ulab.poly` --- Polynomial functions
=========================================
.. module:: ulab.poly
.. method:: polyfit([x, ] y, degree)
Return a polynomial of given degree that approximates the function
f(x)=y. If x is not supplied, it is the range(len(y)).
.. method:: polyval(p, x)
Evaluate the polynomial p at the points x. x must be an array.
:mod:`ulab.extras` --- Additional functions not in numpy
