read decimal and hex from a single file

Hello. I have a file with this format :

1364475492261 *8fe8041658ab056a61a13f827d6e;
1364475492981 *5fe8041640cd9f;
.
.
.

There are those types of values (first in decimal, then ' *' and then either a long hexa code or a short one - those codes have fixed lengths and are identical to those in the example above).

My question is if I can read those from the file and create a matrix with two columns and N rows, for further data processing. My main problem is the 2 data representations (dec and hexa).

Thanks for your time.

fid = fopen('YourFile.txt', 'r');
datacell = textscan(fid, '%f *%[0-9abcdef];');
fclose(fid);

col1_cell = num2cell(datacell{1});
col2_cell = datacell{2};
mat = [col1_cell, col2_cell];

Now "mat" will be an N x 2 cell array, where the first column is numeric and the second is a string. String needs to be used instead of decoding the hex to numeric form because there is no MATLAB numeric datatype that can hold 28 hex digits (14 bytes)

Hey, thanks for the tips. They really helped me construct my program. Cheers.
