3D representation of a histogram
hist3d(mtx,[theta,alpha,leg,flag,ebox]) hist3d(mtx,<opt_args>) hist3d(list(mtx,x,y),[theta,alpha,leg,flag,ebox]) hist3d(list(mtx,x,y),<opt_args>)
matrix of size (m,n) defining the histogram
mtx(i,j)=F(x(i),y(j)), where x
and y are taken as 0:m and
0:n.
where mtx is a matrix of size (m,n) defining the histogram
mtx(i,j)=F(x(i),y(j)), with x
and y vectors of size (1,m+1) and (1,n+1).
This represents a sequence of statements key1=value1,
key2=value2,... where key1,
key2,... can be one of the following: theta,
alpha, leg, flag,
ebox. See plot3d.
see plot3d.
hist3d represents a 2d histogram as a 3D plot.
The values are associated to the intervals [x(i) x(i+1)[ X [y(i)
y(i+1)[
.
