Error with Surf Shading
|
|
|
| Hi,
In the MATLAB Help it says that if I define a surface using
x(i,j),y(i,j) I can define the colour matrix C(i,j) as having one
less row and column than the x and y matrices. This is because if the
shading is set to flat or faceted, there are always 1 less cell
centres than vertices on any one edge. However, when I try this, I
get the following error:
??? Error using ==> surface
Matrix dimensions must agree.
Error in ==> C:\MATLAB6p5\toolbox\matlab\graph3d\surf
.m
On line 68 ==> hh = surface(varargin{:});
Error in ==> C:\Documents and Settings\MBGBLORH\My Documents\PhD
Work\3D Case Generation\Temp Data Files\Plane.m
On line 125 ==> surf(XVN,YVN,PHI)
but...
size(XVN)=[19 73]
size(YVN)=[19 73]
size(PHI)=[18 72]
....so, as long as the shading is not interp, which it isn't, this
should be ok.
Are there any suggestions as to why I get this error?
Thanks in advance,
Oli

| Hi OliH
I usually use surf(x,y,z,c) to give the third z coordinate as well,
otherwise it'll read in c(i,j) as you z ordinate and then have
problems. Set z=zeros(19,73); and see of this helps.
