Nesting for loops and if statements in MATLAB

I have a program in MATLAB that I use two for loops e.g.:

for ....end

for...end. In the 2nd 'for loop' I use an if statement to set a constraint. And I want this if loop to call the first 'for loop' of the program and then continue with the second loop. I mean:

for

    ...
end 

for 

    if..
      call 1st 'for loop'
    end
    ...
end

Is there any way to do this??

There is no such thing as an if loop.

I'm not sure if I understand correctly, but you could put the first for loop into a function.

Function main_func()
   loop_one(params)
   For
      If
       loop_one(params)
      End
   End
End Function

Function loop_one(params)
   For 
   End
End Function

Put the first FOR loop in a function. Then, in your program, call the function, enter the second FOR loop, evaluate the condition and decide whether or not to call the function.

EDIT

You say you tried, but get an error. What did you try and what was the error?? Show simplified code of what you have and what you tried.

how can I put the for loop in a function and how I call it to my script? I try it but always get an error!!
