MEX file to compute 2-D histogram.
[h,vx,vy] = hist2d(x,y)
or
[h,vx,vy] = hist2d(x,y,[x0 dx nx],[y0 dy ny])
Inputs:
x,y data points. {x(i),y(i)} is a single data point. x0 lowest x bin's lower edge dx x bin width nx number of x bins y0 lowest y bin's lower edge dy y bin width ny number of y bins [x0,dx,nx] and [y0,dy,ny] default = [0,1,256]
Outputs:
h histogram matrix. h(i,j) = number of data points
satisfying vx(j) <= x < vx(j+1) and vy(i) <= y < vy(i+1).
vx bin lower x-ordinates (one for each column of h) vy bin lower y-ordinates (one for each row of h)
