You need to more clear about what you mean. Ideally, show a simple example of the input data and the expected result. Include your data and the code you have written so far.

Lets take a example

A matrix z = [1,2,3;4,5,6;7,8,9]

now I have to divide this whole matrix by 9 which is the maximun value in the matrix.

But if the size of matrix is very large, it is very difficult to find maximum value of the matrix manually and then divide the matrix by this maximum value. So how to do this?

Hi Saksham,

According to the description given by you, you can follow the following code for the same.

% Example matrix
matrix = [10, 20, 30; 40, 50, 60; 70, 80, 90];
% Find the maximum value
maxValue = max(matrix, [], 'all');
result = matrix / maxValue;

In this way you will be able to divide the whole matrix by the maximum value present in it.

Incase you have matrix of different dimensions,this code can get the maximum value out of a multi dimensional matrix as well. Then you can divide it by the matrix to get the desired result.

Thanks.
