Hi, when I try to run the example plot:
x = 0:pi/100:2*pi;
y = sin(x);
plot(x,y)
the following error appears:
Undefined function 'fieldnames' for input arguments of type 'double'.
Error in get (line 41)
fields = fieldnames(varargin{1});
Error in newplot (line 61)
fig = getPlotFigure;
Actually the same error appears when I try to plot anything. Please help with R2011b!!

You have created your own routine with the same name as one of the MATLAB routines, and your routine is being called instead of MATLAB's.
I cannot tell at the moment what routine this is happening for, but probably you have your own get.m routine ("get" is a built-in routine for MATLAB so no line number or source would be available if it was the MATLAB "get" that was being invoked.)
which -all get

Exactly, though the routine wasn't written by me. Thanks!
