[Matlab] dec2hex and sprintf problem?

matlab dec2hex

Hi all,

I want to convert a vector of dec to hex and sprintf to a string.
The code is:
%%-------------
data=[11 6 18 14];
sprintf('%c ',dec2hex(data))
%%------------
The output is
ans =

0 0 1 0 B 6 2 E

But what I want is "B 6 12 E", why the output of sprintf shuffle the data?

BTW, I use Matlab 5.3.
Any suggestions will be appreciated!
Best regards,
Davy

matlab sprintf dec2hex

For some reason, Matlab loves to work in columns. dec2hex will output each converted data on it's own line. The sprintf commands is no exception and thus will take the given data by columns. If we take the output of dec2hex([11 6]) for example, Matlab gives us:

ans =
0B
06

Which is then taken into sprintf by columns giving 0 0 B 6. If you try dec2hex([11 6])' the result would be:

ans =
00
B6

Giving an sprintf result of 0 B 0 6. Now there is a problem with what you are trying to do; dec2hex([18 14])' outputs:

ans =
10
2E

Which results as 1 2 0 e in sprintf. The dec2hex command outputs a string.

Hope this helps.
