Hi,

I want increment the iteration 'i' by 3 on each iteration completes and the next iteration statrt from the incremented 'i'.

Code working:

A=[1;2;4;6;7;11;78;12;32;14;32;45];
    
for i=1:3:size(A,1)
disp(i)
% i=i+3;
% disp(i)
disp('.....')
end

but when I use below code, it does not works

A=[1;2;4;6;7;11;78;12;32;14;32;45];
increment=3;
for i=1:size(A,1)
disp(i)
i=i+increment;
%disp(i)
% disp('.....')
end

can't we define the increment like above?

Thanks in advance,

"can't we define the increment like above?"

Nope. You already defined the iteration variable in the for loop definition. What happens inside the loop does not change the for loop definition.

在 MATLAB Online 中打开

In your second cod the iteration steps depends on i, its changing changing the step size 1 as defined in for loop statement

for i=1:size(A,1) %it means i=1,2,3,4...

Replace it with

    for i=1:increment:size(A,1)
        disp(i);
    end

The following vector is same as above

i=1:3:size(A,1);

Which is definitely same as first code.
