How can I convert an array of hex values to a num?

I have an array with '30' '2E' '30' '31' for example, it is a part of a xbee frame, so I would like to get the value (0.01) and I do not know how... Maybe hex2num? But i dont knoe how to insert the values on it.

I know how to do the oposite operation:

>>dec2hex('0.01')

4×2 char array

'30'

'2E'

'30'

'31'

Please help, I'm trying everything...
