I am using simulink user defined function for the control applications. The code does not execute correctly, only the first line executes and remaining code is not getting executing. The code is shown below:

function [Vo,ftw,Rc_ctrl,Dir] = fcn(C,S0,S1,S2)

                                Vo = 0.20; ftw = 10; Rc_ctrl = 0; Dir = 0;
                                if (S0 == 1) && (S1 == 1) && (S2 == 1) && (C <= 2000000)
                                for i=2000000:50000:3500000
                                    if ( (C > i) && (C <= i+50000))
                                    Vo = Vo+0.02; ftw = ftw+1; Rc_ctrl = 0; Dir = 0;
                                    end
                                end
                                end

The variable C is a counter input which counts from 0 to 3500000 at an increment step of 50000. The function inputs S0,S1,S2 are input to the user defined function.

While executing the code only first line executes and remaining lines not getting executing.

Thanking you in advance for your valuable suggestions !!!

Hi,

your first if statement condition includes C<=2000000 but your second if statement wants C to be greater than i, which starts with i=2000000. That's a contradiction.
