In this introduction to NumPy, you'll learn how to find extreme values using the max () and maximum () functions. This includes finding the maximum element in an array or along a given axis of an array, as well as comparing two arrays to find the larger element in each index position.
numpy.maximum(x1, x2, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature]) = <ufunc 'maximum'> #. Element-wise maximum of array elements. Compare two arrays and return a new array containing the element-wise maxima.
Nov 6, 2015 · np.max is just an alias for np.amax. This function only works on a single input array and finds the value of maximum element in that entire array (returning a scalar). Alternatively, it takes an axis argument and will find the maximum value along an axis of the input array (returning a new array). >>> a = np.array([[0, 1, 6], [2, 4, 1]])
Return the maximum of an array or maximum along an axis. Parameters: aarray_like. Input data. axisNone or int or tuple of ints, optional. Axis or axes along which to operate. By default, flattened input is used. New in version 1.7.0.

It’s probably clear to you that the NumPy max function is a function in the NumPy module. But if you’re a true beginner, you might not really know what NumPy is. So before we talk about the np.max function specifically, let’s quickly talk about NumPy. What exactly is NumPy?
The syntax of the np.max function is fairly straight forward, although a few of the parameters of the function can be a little confusing. Here, we’ll talk about the syntactical structure of the function, and I’ll also explain the important parameters.
In this section, I’m going to show you concrete examples of how to use the NumPy max function. I’ll show you several variations of how to find the maximum value of an array. I’ll show you how to find the maximum value of a 1-d array, how to find the max value of a 2-d array, and how to work with several of the important parameters of numpy.max.

Feb 26, 2024 · The maximum() and fmax() functions are part of this vast library, offering two options for element-wise maximum operations over arrays or between scalars and arrays. The primary difference lies in how they handle NaN (Not a Number) values: maximum() – Returns the maximum of two arrays, element-wise.
