WEBexample. S = std(A) returns the standard deviation of the elements of A along the first array dimension whose size is greater than 1. By default, the standard deviation is normalized by N-1, where N is the number of observations. If A is a vector of observations, then S is a scalar.

How To Calculate Standard Deviation in MATLAB? - Online …
WEBAug 7, 2023 · In this MATLAB code, we start by creating an input array ‘A’. Then, we create a weight vector ‘w’. Next, we calculate the standard deviation of the array A along the rows (dim = 1) and along the columns (dim = 2) by using the ‘std’ function. The results are stored in the ‘S_r’ and ‘S_c’ variables.
