Hello I have a hex cell array and I indexed them.
For example I have 'A7' and when I use hex2dec, it gives me nonsense result which is -7.7452e-121. how can I get exact result? I mean I want to see that hex A7 = decimal 167.
Thank you.

hex2num inteprete 'A7' as IEEE double number (64bit) with mantissa and exponents. So padding 0's before 'A7'. The string is in a different order (from last byte to first byte) so it looks like (actually not) padding 0's after 'A7'.

x ={'3A', 'F1', 'CF', '4C'}
x = 1×4 cell array
{'3A'} {'F1'} {'CF'} {'4C'}
y = cellfun(@hex2dec, x)
y = 1×4
