W-M function to plot 3d fractal surfaces

I want to plot a fractal 3D surface using W-M function.
Here is my result:
It is different from fractal surfaces from other journal articles like this:
piture from An adhesive wear model of fractal surfaces in normal contact, X. Yin, K. Komvopoulos
I know maybe it can be resolved by increasing x and y number, but it takes a lot of time.
So, can anyone help me optimize the code?
Thanks!

You need to use loops in myF.m file....read about vectorizing the calculations. Read about element by element calculations.

Hi,
Here are corrected codes of yours. One more important note that it is not a good practice to call your m-file with a MATLAB built-in fcn or command name, e.g., plot, grid, legend, exp, clc, ....
Good luck.

It looks better than before. It now looks like this:
But it is still different from X. Lin's result. Maybe the data is optimized by some method to remove saliens.
Have you notice the units of X and Y? it's 'um' in Lin's paper, and 'm' in your program. Try again.

Hi
Just wanted to check up if you have already solved the problem yet. Thanks!
