File storage problem - Anil B.V. - May 10 16:09:00 2001

Hi I am working on EZW coding. The first part that is subband decomposion is done in MATLAB. Now I have an array of wavelet coefficients with size 256 -by- 256. I need to store this array in a file with only 8 bits/coefficient in the signed char format. The remaining work is done on C. I have used the following commands: Z = fopen('e:\wavelet\EZW\matrix.raw','wb'); COUNT = fwrite(Z,coeffs1,'char'); Where coeffs1 is the matrix converted to character prior to the above command. But this gives only 1-D 1-256 Empty matrix. Please help in this regard. Anil __________________________________________________ |
