How can I convert a double-precision hexadecimal back into a double?
That is, given s, created from the double x as such:
s = sprintf('%bx',x)
How can I recover x?

>> x=rand
x =
0.126986816293506
>> s = sprintf('%bx',x)
s =
3fc0411a9f807b7c
>> y=hex2num(s)
y =
0.126986816293506

That's it! I tried this and thought it wasn't working, but I had previously set "format hex". Thanks.
