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!!

在 MATLAB Online 中打开

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.)
