how to find max and min using for loop, and if condition, without using the max and min function?

so i have this text file (hwk3_input.txt) that is very large, 1140 X 1 I have a matrix, i called this matrix A. I need to use for loop to find the max and min value

this is what i got so far but i'm not understanding how to set it up.. can someone please help me?!

A= load('hwk3_input.txt');
n = length(A);
for i = 1:n 
    if A(i) < length(i)
        length(i)=A(i)
    end    
end

You need to set a value called theMax and set it to -inf before the loop:

theMax = -inf;
theMin = +inf;

Then in the loop check if A(i) is less than theMin or more than theMax.

if A(i) < theMin

If it is, set the min or max to the current value of A(i). Give it a try and if you need more help with your homework give you most recent code version.

Can someone help me? How to find minimum of an array using for loop?

[Image Analyst]

If m is your array:

mMin = inf;
for k = 1 : numel(m)
    if m(k) < mMin
        mMin = m(k);
    end
end

This should work for any number of dimensions.
