See the doc on that one

See the doc on that one Hey Neil, i tried the below code. It is writing but i dunno why but the written data is not in hexadecimal format. It is writing in exponential format. fid = fopen ('in_data.txt','w'); fprintf(fid, '%x \n', refsig); fclose (fid); The total size of refsig is 1x1024. thanks

Firstly don't use %x use %s since you want to write the hex string and not the numerical representation of the string put your hex data in a cell array a = cellfun(@dec2hex,num2cell(1:200),'uniformoutput',false) fid = fopen('test.txt','wt') fprintf(fid,'%s\n',a{:}) fclose(fid) replace 1:200 with your decimal data matrix |
