MATLAB, how to change loop index inside for loops [duplicate]

Question

I have a loop like this:

b = 1;
for c = 1 : 10;
  if b == 1
      c = 1 + 3
  end
end

What do I need to do to make to change c? Because as I read through the help, MATLAB resets the loop counter c after it reaches end.

Is there any way to change the value of the loop counter from within a for loop?

Answer 1

you could use a while loop instead of a for loop.

something like (I'm guessing you want to add 3 to c otherwise c = 4 could replace that line below)

b = 1;
c = 1;
while(c < 10)
    if b == 1
        c = c + 3
    end
end
