Is there a way to find the max value in an array without using the "max" command?

My professor wants us to create a function to find the max value in an array x (max=maxvalue(x)). He said we are not allowed to use the built-in max command. But what else is there?

The max function is just an implementation of an algorithm that compares the values in the vector to find the one with the highest value. You assignment, therefore, is to implement your own algorithm. I'd perhaps start with
if x(1) > x(2)...

with the help of for and if, we can create a function to find max value in given array. If it is vector, use two for loop for row and col.
function max_Value = find_maxValue(Input)
max_Value = Input(1);
for i1 = 1 : length(Input)
if Input(i1) > max_Value
max_Value = Input(i1);

Let A - your array.
B = A(:);
max_value = B(all(B - B' <= 0));

sort() and take the endpoint.
Or loop comparing each entry to the largest so far and if the current entry is greater then update the running maximum.
