function to make uniform a non-uniform distribution of input data

Imagine a distribution of data points which are biased in some position and non-uniform. I am looking for a matlab code which first evaluate if the data points are uniform or not and if not, second, make it uniform. e.g. function takes 100 of non-uniform distributed data points and remove 20 points and make it a uniform distribution of 80 points. The should be able to do it for n-dimension (high dimension)
