Hi,
I want to extract difference between two point cloud data
To extract difference in point cloud instead of using nearest neighbour in Matlab is there any other approach we can follow because it is taking a lot of time to me to extract different so if there is an efficient way to extract the difference between two point clouds please let me know

I understand that you are looking to estimate the difference between two point clouds by extracting difference. I assume that you mean extracting and comparing features between two point clouds. You can perform this task by using the extractFPFHFeatures function to extract the features and the pcmatchfeatures function to find matching features between both of the point clouds. The pcmatchfeatures documentation contains an example that shows you how to perform this.

I am using R2020a and refered extractFPFHFeatures but getting and error
undefine function 'extractFPFHFeatures' for input argument type of 'pointCloud'
How to resolve this?

This feature is available from R2020b. I suggest that you refer to Point Cloud Registration. I think those features are present in R2020a.
