Question

Write a function max_matrix(M) that takes in a non-empty matrix (a 2-dimensional array) of real numbers M and returns its maximum value. You must use loops in your code.

In python

Expert Solution

Step 1: Algorithm :

Initialize a variable max_value to the value of the first element in the input matrix M[0][0].
Check if the input matrix M is empty. If it's empty, raise a ValueError indicating that the input matrix is empty.
Iterate through each row in the matrix M using a nested loop.
For each row, iterate through each element in the row using another loop.
Inside the inner loop, compare the current element element with the max_value.
If the element is greater than the max_value, update max_value with the value of the element.
Continue iterating through all elements of the matrix, comparing each one with max_value and updating max_value when a larger element is found.
After iterating through all elements of the matrix, max_value will hold the maximum value in the entire matrix.
Return max_value as the result.
