How do I create a for loop in MATLAB?

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?

[Abderrahmane Walid AISSANI]

hi I am trying to create several variables using the for loop

    % for k=1:1:10
      tab_k = csvread('');
      end

in fact the code is wrong but I want to iterate the "k" in the name of the variable but I can't find how to do that .

thank you .

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)
       disp(A(i))
end

For more examples using for loops, see:

As far as I know the for-loop is even more excellent than what says in this text. As far as I know the matlab for-loop works similar to the for_each-loop that can be seen in many programming languages these days, or maybe the range-for in c++11. For example is this possible,

a = aObjArray;
for k = a
  a.modify();
end

This is not really clear from the documentation, so I thought this would be a valuable comment.

You can get help from the documentation of Matlab:

There you find examples and explanations.

Thanks so much. Finally, I understood what is for loop.

For loop repeat itself for a given number of input. The syntax for “For Loop Matlab” is

for variable = expression
Program Statement
end

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); 
end

Initial value : Step : Final value

for x = 1:2:10
fprintf('value of x: %d\n', x); 
end

Value Array

for x = [1 4 6 8 90]
disp(x) 
end
