efficient hex2bin function
I have a huge dataset that is coded in hexadecimal. I need to translate it i
nto binary to decode it. I have been using dec2bin(hex2dec(dataset)) which t
akes a long time for my data (~15 minutes). An example dataset is:
So my question is: does anyone have an efficient way to do the conversion? A
direct hex2bin function would be nice, I just haven't been able to figure o
ut how to vectorize the character substitutions (i.e. a 3 in hex becomes a 0
011 in binary).
Thanks for any ideas.

- I think my post made it clear that I was trying to go beyond the solutions p
resented in the previous thread. If after re-reading my post you have any id
eas, I'd be grateful. Thanks.

You could always turn your entire HEX stream into a binary stream
using lookup tables. And then reshape to whatever word length you
