I receive the following error messages when running the following scripts using mesh or surf commands with MATLAB Student Version 7.10 (R2010a) installed on a stand-alone PC running Windows XP.

% Script Filename: Prob271.m
x=-1:0.1:3;
y=1:0.1:4;
[X,Y]=meshgrid(x,y);
Z=X.*Y.^2./(X.^2+Y.^2);
mesh(X,Y,Z)
xlabel('x'); ylabel('y'); zlabel('z')

??? Error: File: usev6plotapi.m Line: 1 Column: 1
The input character is not valid in MATLAB statements or
expressions.

Error in ==> mesh at 57
[v6,args] = usev6plotapi(varargin{:},'-mfilename',mfilename);


% Script Filename: Prob272.m
x=-1:0.1:3;
y=1:0.1:4;
[X,Y]=meshgrid(x,y);
Z=X.*Y.^2./(X.^2+Y.^2);
surf(X,Y,Z)
xlabel('x'); ylabel('y'); zlabel('z')

Doug,
MatLab comes with a gui.m example (I'm pretty sure) that uses the mesh, peaks, and contour functions. Call guide and open existing gui. If not, check this out

What do you receive as output from the following commands?

which -all usev6plotapi.m
dbtype 1:10 usev6plotapi.m
