function H = hist2d(D,Xn,Yn,[Xlo Xhi],[Ylo Yhi])
Calculates and draws the 3D histogram of 2 Dimensional input data D.
Counts number of points in the bins defined by
X = linspace(Xlo,Xhi,Xn) and
Y = linspace(Ylo,Yhi,Yn)
D must be a 2 column or 2 row matrix or an array of complex numbers
[Xlo Xhi],[Ylo Yhi] are optional and default to the min and max of
the input data
Xn and Yn are optional and default to 20
Example:
hist2d([randn(1,10000); randn(1,10000)])
Really just a copy of 2D Histogram, by Rey Patlolla, but with default arguments, optionally complex input and draws a 3D histogram. |
