This function is used to make density plot of scatter point data, which is based on build-in function hist3 in matlab. So the inputs of the function densityplot can refer to hist3. Some examples are given as below:
x = randn(2048, 1);
y = randn(2048, 1);
x(1:512) = x(1:512) + 2.75;
x(1537:2048) = x(1537:2048) + 2.75;
y(1025:2048) = y(1025:2048) + 2.75;
densityplot(x, y, [20,20]);
The advantage of this function is the high efficiency and its code is very simple. You can modify it according to your own requirement. Enjoy.
