Hello,
I'm trying to get the function ksdensity to return a matrix instead of a vector when I use it for a bivariate input (signal of I and Q).
The problem is that ksdensity only returns a vector even if the points are inputted as a 2 column matrix.
Can anybody help ?

Hi,
From my understanding you are trying to get a 2D output from the bivariate data and using the ksdensity function you are getting a vector. The following MATLAB Answer would likely help you achive your objective.

Hi,
You are right in your understanding. But the difference is that for my data (Baseband modulated signal) the variables are not independent, that's why I cant generate KSD for each var and multiply their pdfs.
