I can't use function jpeg2im

when i type i.e. >> f1=jpeg2im(c1);

 i face these errors

??? Attempt to execute SCRIPT unravel as a function: C:\Program Files\MATLAB\R2010b\bin\unravel.m

Error in ==> huff2mat at 61 x = unravel(y.code', link, m * n); % Decode using C 'unravel'

Error in ==> jpeg2im at 42 x = huff2mat(y.huffman); % Huffman decode.

and unravel.m has not any code.

%UNRAVEL Decodes a variable-length bit stream. % X = UNRAVEL(Y, LINK, XLEN) decodes UINT16 input vector Y based on % transition and output table LINK. The elements of Y are % considered to be a contiguous stream of encoded bits--i.e., the % MSB of one element follows the LSB of the previous element. Input % XLEN is the number code words in Y, and thus the size of output % vector X (class DOUBLE). Input LINK is a transition and output % table (that drives a series of binary searches): % % 1. LINK(0) is the entry point for decoding, i.e., state n = 0. % 2. If LINK(n) < 0, the decoded output is LINK(n); set n = 0. % 3. If LINK(n) > 0, get the next encoded bit and transition to % state [LINK(n) - 1] if the bit is 0, else LINK(n).
