Which MATLAB version are you using? The ability to specify a size matrix in sym() is quite new, R2010b I think it is; with older MATLAB releases the error message for trying it might be strange.

7.0.0.19920(R14)

is there any other method to do the same....

That version is definitely too early to create a symbolic matrix using that syntax.

Sean's answer is good if you want to create A as an array initialized to particular values. If you want to create an array of symbols, there are ways involving loops or expressions with meshgrid()
