Draw the output shape

hi.

I want to know how to draw the shape that is attached in the MATLAB software.This figure is in one article, and the author of the article acknowledged that it was an output from MATLAB. But I have no idea.

Please guide me.

Thanks

mohammad - if the attached graph is from a paper/article, then there is probably an equation for it. Try asking the author for that equation.

ِDear Geoff Hayes,

But it seems that I did not convey my intention to you correctly. Yes, it has an equation, and I have drawn it. But the way I draw is different from drawing graphically. I don't know what this kind of drawing is in MATLAB. Because it doesn't seems to follow a command like a simple plot. I hope I have stated my point correctly.

With respect,

You probably need to show us the code you have written that creates the plot and discuss the differences between what you are observing and what you desire. Also, include any sample data that you have used.
