Hi,
Is there a command to save files through Matlab? I have csv files (containing dates and double) and would like to save them into another folder. These files were downloaded from a data colletion software and for some reason, have quotation marks around every value, ex: A= ["3", "2008/01/02", "c31213", "0"; "5", "2008/01/05", "c36465", "1"; "6", "2008/01/54", "c31587", "4";]
this file is very hard to work with in matlab, but I noticed that once the file is resaved, the quotation marks disapear. this is why I want to resave them.
Simply opening the file and writing them into another will not work because again, reading the quotation marks is impossible.

csvwrite() or dlmwrite()
BTW, you could easily get rid of the double quote symbol.
A='"3", "2008/01/02", "c31213"';
B=strrep(A,'"','')
You could do that too on a file with find-and-replace

A = fileinput(FILENAME); A(A=='"')=[]; fid = fopen(NEWFILENAME,'w'); fwrite(fid,A); fclose(fid)
