Is there any way to estimate thickness variation in my ~ 2"X 4" steel plate approximately 4 mm thick?. I have the 3D point cloud scanned and imported into MATLAB. Thanks.

Thank you, how then is thickness varition estimated from such plots?
Thanks

Create two surfaces and substract each from another

If I understand the question correctly you were asking about the thickness variation across whole slab. so I would suggest you to have a reference point by drilling a hole through the sample and then gather your point cloud data for both front and back of your sample.
Later you can align the drill hole from the point cloud data and obtain the thickness variation information.
Also consier approximate mean thickenss as the seperation while combining the front/back point cloud data.
