The simplest way to stop you going crazy is simply to look in the documentation. Under Matlab -> Language fundamentals -> Data Type -> Data Type conversion you'll find the documentation for hex2dec.

d = uint16(hex2dec('2A5F'))

Also have a look at converting string to numeric.

Also for OP that is seemingly almost totally unknown any longer is

>> lookfor hex
dec2hex                        - Convert decimal integer to hexadecimal string.
hex2dec                        - Convert hexadecimal string to decimal integer.
hex2num                        - Convert IEEE hexadecimal string to double precision number.
num2hex                        - Convert singles and doubles to IEEE hexadecimal strings.

when one has a subject area but not sure of the function name actually looking for...
