matlab count elements in matrix

To count the number of elements in a matrix in MATLAB, you can use the numel function. Here's an example:

matrix = [1, 2, 3; 4, 5, 6; 7, 8, 9];
num_elements = numel(matrix);

In this example, the numel function is used to count the number of elements in the matrix variable. The result will be stored in the num_elements variable.

Please note that the numel function counts the total number of elements in the matrix, including both rows and columns.
