The provided MATLAB code defines a function called custom_max that takes a vector v as input and returns the maximum value in the vector. Here's how the code works step by step:

1. Initialization: The variable M is initialized to the first element of the vector v. This will serve as the current maximum.

2. Iteration: The for loop iterates over each element (x) in the vector v.

3. Comparison and Update: For each element x in the vector, it checks if x > M. If this condition is true, it updates M to be x.

4. End of Loop: After the loop completes, the variable M contains the maximum value in the vector v.

5. Return Value: The function does not explicitly return M, so it will not produce an output as written. To fix this, the function should include a return statement (e.g., custom_max = M).

Note:

• As written, this code computes the maximum value manually using a loop and direct comparison. However, MATLAB has a built-in max function that can achieve the same thing more efficiently: M = max(v).
• Without a return statement, the function would not provide a usable result when called from the MATLAB command prompt. To make it functional, you would need to return the variable M.

Corrected Code:

function M = custom_max(v)
    M = v(1); 
    for x = v 
        if x > M
            M = x; 
        end
    end
end

This version computes and returns the maximum value in v.
