3D plot of a surface in Matlab
3D plot of a surface in Matlab
Create a surface of function mesh
Graphics 3-D line plot
Graphics 3-D contour plot
Draw contours in volume slice planes
For 3-D shaded surface plot use command:
surf(Z)
surf(Z,C)
surf(X,Y,Z)
surf(X,Y,Z,C)
surf(...,'PropertyName',PropertyValue)
surf(axes_handles,...)
h = surf(...)
surf(Z) creates a three-dimensional shaded surface from the z components in matrix Z, using x =
1:n and y = 1:m, where [m,n] = size(Z). The height, Z, is a single-valued function defined over a
geometrically rectangular grid. Z specifies the color data, as well as surface height, so color is
proportional to surface height.
surf(Z,C) plots the height of Z, a single-valued function defined over a geometrically rectangular
grid, and uses matrix C, assumed to be the same size as Z, to color the surface. See Coloring
Mesh and Surface Plots for information on defining C.
surf(X,Y,Z) uses Z for the color data and surface height. X and Y are vectors or matrices
defining the x and y components of a surface. If X and Y are vectors, length(X) = n and
length(Y) = m, where [m,n] = size(Z). In this case, the vertices of the surface faces are (X(j),
Y(i), Z(i,j)) triples. To create X and Y matrices for arbitrary domains, use the meshgrid function.
surf(X,Y,Z,C) uses C to define color. MATLAB® performs a linear transformation on this data
to obtain colors from the current colormap.
surf(...,'PropertyName',PropertyValue) specifies surface properties along with the data. For a list
of properties, see Chart Surface Properties.
surf(axes_handles,...) plots into the axes with handle axes_handle instead of the current axes
(gca).
h = surf(...) returns a handle to a chart surface graphics object.
