Sum the Elements of a Matrix Using thesum()Function in MATLAB To find the sum of all the elements of a matrix, we can use thesum()function. In the case of a matrix, we have to use thesum()function two times, one for rows and one for columns, but in the case of a vector, we...
This MATLAB function takes a matrix or cell array of matrices, x, and returns the sum, s, of all squared finite values in x, and the number of finite values, n.

Create a 3-D array whose elements are 1. A = ones(4,3,2); To sum all elements in each page ofA, specify the dimensions in which to sum (row and column) using a vector dimension argument. Since both pages are a 4-by-3 matrix of ones, the sum of each page is 12. ...
