In Python, the numpy.gradient() function approximates the gradient of an N-dimensional array. It uses the second-order accurate central differences in the interior points and either first or second-order accurate one-sided differences at the boundaries for gradient approximation. The returned gradient hence has the same shape as the input array. Here is the argument table of … Read more
This article shows you how to calculate the standard deviation of a given list of numerical values in Python. Definition and Problem Formulation The standard deviation is defined as the square root of the variance. In case you’ve attended your last statistics course a few years ago, let’s quickly recap the definition of variance: variance … Read more
In Python, the numpy.diff() function calculates the n-th discrete difference between adjacent values in an array along with a given axis. For higher-order differences calculation, numpy.diff() runs recursively to the output of the previous execution. Here is the argument table of numpy.diff(): If it sounds great to you, please continue reading, and you will fully … Read more
