Calculation of Enormous Numbers

Greetings!

I am trying to calculate some truly enormous numbers but I am running into difficulties using the symbolic toolkit. I am looking to calculate and do further operations to numbers around 2^1000. From the Matlab support literature they suggest I use the Symbolic Toolkit. I ran the following snippet:

syms Z;
Z = sym('2^1000')

The output is the following:

Warning: Support of strings that are not valid variable names or define a number will be removed in a future release. To
create symbolic expressions, first create symbolic variables and then use operations on them.

Z =

I am not sure how to work around this warning. Perhaps there is a better way to approach this?

I would appreciate any help!

Thank you!

Another way:

digits 500
Z = vpa(2)^1000

Or see John D'Errico's submissions in the FEX:

Thank you. I figured there was a way to do it.
