I have symbolic math toolbox installed in my Matlab. However, when I type in the standard A = sym(‘A’, dim) [also noted in mathworks site] code it gives an error. Why is that so ?

A = sym(‘A’, [2 4])

??? Error using ==> error
Formatted arguments cannot be non-scalar numeric matrices.

Error in ==> sym.sym>assumptions at 2180
error(‘symbolic:sym:sym:errmsg1′,’Second argument %s not recognized.’,a);

Error in ==> sym.sym>tomupad at 2148
assumptions(S,x,a);

Error in ==> sym.sym>sym.sym at 114
S.s = tomupad(x,a);

    I think you have an older version of Matlab.

    The documentation is for R2012b.

    In my R2010a version, the documentation does not show this capability.
