Is there a program that yields a 2 dimensional histogram,
like the vector histogram hist.m, but in two dimensions?
I have 27,000 datapoints of x, y
>> size(datapoints)
rows = 27000
columns = 2
where datapoints(:,1) are all the x values and
datapoints(:,2) are all the y values
for this example x and y are equal range centered on zero.
I want to obtain the histogram of these datapoints.
The program I wrote, I can't find fault with but keeps
yielding strange patterns where there should be even
distribution.
Did I miss one in the manual, or does anybody have a
program like this?
Keep in mind that I'm using octave 2.1.50a so that I can
keep the excellent speed and plotting capaiblities to show
the results.
