I am completely lost in for loops, I just don't get it. The book and my professor haven't helped much. Where can I get help?

A basic for loop in MATLAB is often used to assign to or access array elements iteratively. For example, let’s say you have a vector A, and you want to simply display each value one at a time:
A = [3 6 9 4 1];
for i = 1:length(A)

For loop repeat itself for a given number of input. The syntax for “For Loop Matlab” is
for variable = expression
Program Statement
In the above syntax, the expression has one of the following forms.
Initial value : Final value
for x = 1:10
fprintf('value of x: %d\n', x);
Initial value : Step : Final value
for x = 1:2:10
fprintf('value of x: %d\n', x);
Value Array
for x = [1 4 6 8 90]
