If the number in the cell is higher than the median of all the numbers in the matrix then the number in the cell wil be replaced by a 1 else by a 0

Hi Ziad,

You can use "median()" function in MATLAB to compute the median of the matrix.
Further you can create a logical matrix (same size as original matrix), fill in the values using logical operation comparing with the median value. (refer to 2nd documentation attached)

Refer to the documentation:

Hi Ziad,

Assuming you have a matrix named 'matrix' :

% Calculate the median of all the numbers in the matrix
medianValue = median(matrix(:));
% Create a new matrix where numbers greater than the median are replaced by 1, and others by 0
resultMatrix = zeros(size(matrix));  % Initialize with zeros
resultMatrix(matrix > medianValue) = 1;  % Set values greater than median to 1

Hope it works!
