plot3d3 — mesh plot surface defined by rectangular facets
plot3d3(X,Y,Z [,vect,theta,alpha,leg,flag,ebox]) plot3d3(X,Y,Z, <opt_args>)
| X,Y,Z | : 3 real matrices |
| vect | : real vector |
| flag | : flag=[type,box], type and box have the same meaning as in plot3d. |
| <opt_args> | : This represents a sequence of statements key1=value1, key2=value2,... where key1, key2,... can be one of the following: vect,flag (see above), theta, alpha ,leg,ebox (see plot3d) |
plot3d3 performs a mesh plot of a surface defined by rectangular facets. (X,Y,Z) are three matrices which describe a surface. The surface is composed of four sided polygons.
The X-coordinates of a facet are given by X(i,j),X(i+1,j),X(i,j+1),X(i+1,j+1). And similarly Y and Z are Y and Z coordinates.
The vect vector is used when multiple surfaces are coded in the same (X,Y,Z) matrices. vect(j) gives the line at which the coding of the jth surface begins. See plot3d2 for a full description.
u = linspace(-%pi/2,%pi/2,40); v = linspace(0,2*%pi,20); X = cos(u)'*cos(v); Y = cos(u)'*sin(v); Z = sin(u)'*ones(v); plot3d3(X,Y,Z);
