How to compare all matrix cells to the median value?

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,

1. You can use "median()" function in MATLAB to compute the median of the matrix.
2. 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:

1. median - MATLAB - Mathworks
2. Find Array elements that meet a particular condition - MATLAB - Mathworks

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!
