    NumPy sqrt() in Python – Tutorial

    Python NumPy module is used to work with multidimensional arrays and matrix manipulations. We can use NumPy sqrt() function to get the square root of the matrix elements.

    Python NumPy sqrt() Example

    Copy Code 
    

    import numpy

array_2d = numpy.array([[1, 4], [9, 16]], dtype=numpy.float)

print(array_2d)

array_2d_sqrt = numpy.sqrt(array_2d)

print(array_2d_sqrt)

Output:

[[ 1.  4.]
 [ 9. 16.]]
[[1. 2.]
 [3. 4.]]

    Let’s look at another example where the matrix elements are not square of integers. This time we will use the Python interpreter.

    Copy Code 
    

    >>> import numpy
>>> 
>>> array = numpy.array([[1, 3], [5, 7]], dtype=numpy.float)
>>> 
>>> print(array)
[[1. 3.]
 [5. 7.]]
>>> 
>>> array_sqrt = numpy.sqrt(array)
>>> 
>>> print(array_sqrt)
[[1.         1.73205081]
 [2.23606798 2.64575131]]
>>>

    NumPy sqrt() Infinity Example

    Let’s see what happens when we have infinity as the matrix element.

    Copy Code 
    

    >>> array = numpy.array([1, numpy.inf])
>>> 
>>> numpy.sqrt(array)
array([ 1., inf])
>>>

    Complex Numbers

    Copy Code 
    

    >>> array = numpy.array([1 + 2j, -3 + 4j], dtype=numpy.complex)
>>> 
>>> numpy.sqrt(array)
array([1.27201965+0.78615138j, 1.        +2.j        ])
>>>

    Negative Numbers

    Copy Code 
    

    >>> array = numpy.array([4, -4])
>>> 
>>> numpy.sqrt(array)
__main__:1: RuntimeWarning: invalid value encountered in sqrt
array([ 2., nan])
>>>

    The square root of a matrix with negative numbers will throw RuntimeWarning and the square root of the element is returned as nan.
