How to draw a line in if condition and plotting

Hello,

My code is:

dx=0.01;

x=0:0.01:1;

dt=0.0001;

for nt=1:10001

t=(nt-1)*dt

...

    if t==0
        divider(:) = NaN;
    end
    if t>0 && t <=0.01
        divider(1) = 0.25;
        for i=2:ii
            divider(i) = NaN;
        end
    end
    if t>0.1 && t <=0.02
        divider(1) = 0.25; divider(2) = 0.25;
        for i=3:ii
            divider(i) = NaN;
        end
    end
    if t >=0.03
        divider(:) = 0.25;
    end

 plot(x,divider,'g','Linewidth',4.4);

end

I want to see the divider in t=0, t=0.01, t=0.02,.. and it must be a horizontal line changing with time. It should be increased gradually with x axis. But it is not. How can I draw it pls?

Hi,

In the code that you have provided above, the variable 'ii' is undefined. It is a good practice to predefine the variable 'divider', Add the line provided below before the for loop begins.

divider=zeros(1,length(x));

In the last if condition: As per the code provided I can see that the variable 'divider' has only 0.25 as the value and this will plot only a straight line 0.25. Please provide more information on the output that you are expecting. Also please post a sample image of the output that you are expecting.

Thanks I have figured the problem out.
