Sorting, Searching, and Counting

The following tables show sorting and searching functions provided by NLCPy.

Sorting

`nlcpy.argsort`	Returns the indices that would sort an array.
`nlcpy.sort`	Returns a sorted copy of an array.

`nlcpy.argmax`	Returns the indices of the maximum values along an axis.
`nlcpy.argmin`	Returns the indices of the minimum values along an axis.
`nlcpy.nanargmax`	Returns the indices of the maximum values in the specified axis ignoring NaNs.
`nlcpy.nanargmin`	Returns the indices of the minimum values in the specified axis ignoring NaNs.
`nlcpy.argwhere`	Finds the indices of array elements that are non-zero, grouped by element.
`nlcpy.nonzero`	Returns the indices of the elements that are non-zero.

Counts the number of non-zero values in the array a.
