nlcpy.fmin

nlcpy.fmin = <ufunc 'nlcpy_fmin'>

Computes the element-wise minimum of the inputs.

Compare two arrays and returns a new array containing the element-wise minima. If one of the elements being compared is a NaN, then the non-nan element is returned. If both elements are NaNs then the first is returned. The latter distinction is important for complex NaNs, which are defined as at least one of the real or imaginary parts being a NaN. The net effect is that NaNs are ignored when possible.

Parameters
x1, x2array_like

Input arrays or scalars, containing the elements to be compared. If x1.shape != x2.shape, they must be broadcastable to a common shape (which becomes the shape of the output).

outndarray or None, optional

A location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshly-allocated array is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs.

wherearray_like, optional

This condition is broadcast over the input. At locations where the condition is True, the out array will be set to the ufunc result. Elsewhere, the out array will retain its original value. Note that if an uninitialized out array is created via the default out=None, locations within it where the condition is False will remain uninitialized.

**kwargs

For other keyword-only arguments, see the section Optional Keyword Arguments.

Returns
yndarray

The fmin of x1 and x2, element-wise. If x1 and x2 are both scalars, this function returns the result as a 0-dimension ndarray.

fmax

Computes the element-wise maximum of the inputs

minimum

Computes the element-wise minimum of the inputs.

amin

Returns the minimum of an array or minimum along an axis.

nanmin

Returns the minimum of an array or minimum along an axis, ignoring any NaNs.

Note

The minmum is equivalent to nlcpy.where(x1 when neither x1 nor x2 are nans, but it is faster and does proper broadcasting.

Examples

>>> import nlcpy as vp
>>> vp.fmin([2, 3, 4], [1, 5, 2])
array([1, 3, 2])
>>> vp.fmin(vp.eye(2), [0.5, 2]) # broadcasting
array([[0.5, 0. ],
       [0. , 1. ]])
>>> vp.fmin([vp.nan, 0, vp.nan],[0, vp.nan, vp.nan])
array([ 0.,  0., nan])
