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?

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.

Have you notice the units of X and Y? it's 'um' in Lin's paper, and 'm' in your program. Try again.
