Subject: gradient error

Hi ,

I have a vector 'a':

a = [32    45    54]

When I use the gradient function as follows , I get no errors from Matlab:

>> gradient(a);

ans =

    13    11     9

But I want the dF/dx and dF/dy components from the gradient , but I get the follwoinf error:

>> [Fx, Fy]     =   gradient(a);
Error in ==> gradient at 49
[msg,f,ndim,loc,rflag] = parse_inputs(f,varargin);

??? Output argument "varargout{2}" (and maybe others) not assigned during call to "C:\Program
Files\MATLAB\R2010a\toolbox\matlab\datafun\gradient.m>gradient".

Any help appreciated.
