How I accept generated [x,y] samples that fall into a probability density function or an equivalent area?

I generate samples in 2-d space, i.e. x,y coordinates. I have a normal pdf and I want to keep/accept the samples that fall inside the pdf. Let as denote this area W. Is there a specific command for this? How can I implement it? I found in Matlab inpolygon command , but it works only for polygonal region and not on curves, such as pdf .

I'm not sure you mean "fall inside the pdf" since, of course, all values generated must come from the PDF. I think you mean "fall inside the area", presumably one defined by some limits on x and y
% Get x and y somehow
if x < x1 || x > x2 || y < y1 || y > y2
% Coordinate is out of bounds. Skip this one.
continue;
end
% Else do something with it.
