hist3d(2)

NAME
hist3d - 3D representation of an histogram

CALLING SEQUENCE
hist3d(f,captions,view)

PARAMETERS

f   : matrix or list :

    -   matrix f(i,j)= F(x(i),y(j)), x and y taken as 0:m and 0:n, ( (m,n) is the size of f).

    -   list of size 3; list(f,x,y) where f is a matrix of size (m,n) and x and y two vectors of size (1,n+1) and (1,m+1)

captions
    : vector of strings : captions=[legx,legy,legz]

view
    : vector of size view=[gain,theta,phi [,gray]]

    gain
        : scaling factor on the Z-axis. If gain=0, the value of gain is computed automatically.

    theta,phi
        : spherical angles of the observation point in radian. The default value is [0 ,%pi/4 ,%pi/3].

    gray
        : Optional parameter giving the gray level used to plot the surface.

DESCRIPTION
3 dimensional representation of an 2d histogram : the values associated to the intervals ([x(i) x(i+1)[ X [y(i) y(i+1)[)
