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.
