Indexing in for loop

How to use indexing in a for loop?

Answer 1

[Shivani Dixit]

Assuming you are using MATLAB, the indexing begins from 1. An example for for loop is explained below:

arr = [1 2 3 4 ] % assuming an example array
for i=1:length(arr)
    x=arr(i) % we access elements using paranthesis
end

You can leverage the mathwork documentation for more information on indexing in loops in matlab :

You can read the documentation instead asking such simple questions.

A = rand(10) ; 
[m,n] = size(A) ;
for i = 1:m
    for i = 1:n
        a = A(i,j) 
    end
end
