WebAug 11, 2024 · Mean of matrix is = (sum of all elements of matrix)/ (total elements of matrix) Note that this definition doesn't require matrix to be sorted and works for all matrices. Median of a sorted matrix is calculated as: 1. When n is odd median is mat [n/2] [n/2] 2. When n is even, median is average of middle two elements. WebDescription of Mean Function in Matlab 1. M = mean (X) This function will return the mean of all the elements of ‘X’, along the dimension of the array which is non-singleton i.e. the size is not equal to 1 (It will consider the first dimension which is non-singleton). mean (X) will return the mean of the elements, if X is a vector.
