It's not clear what you're asking or what's not working. Code is helpful but when there's a lot of code and no explanation of what's wrong, we don't know where to start. Minimize the time we need to spend helping you by clearing defining the problem.

If you don't make use of subplot, but use 'plot' instead in different figures. Does it work?

Hi Darkhan,

It seems the condition (‘d > s’) which you put in while loop is not satisfied, so the subplot command is not executed. Select the value of ‘d’ and ‘s’ such that the condition should satisfy in order to plot your values.

For example, set v=5, H=6 and d=25, you will get your required plot.

Hope it will help.
