MATLAB: How to write percentage sign into a txt file

fprintfMATLAB

I'm trying to generate an html file using fprintf. The issue is that % is causing lots of issues, because it is used by the system to detect the type of the info (integer, text, etc.). So how do I get around the issue?

fprintf(fid, '<td width="20%">%s</td>\n', B{i,2});

Leon - try using two %

 fprintf(fid, '<td width="20%%">%s</td>\n', B{i,2});

See the special characters section from fprintf.

MATLAB: How to force a number to be displayed as a string

Are the numbers stored as numbers or character vectors in MATLAB?

class(A{i,9}) % double or char?

If the answer is double, then you want to use %d in your format string instead of %s.

fprintf(fid, '<td width="6%%"><a href="https://www.abcdef.com/%d">%d</a></td>\n',  A{i,9}, A{i,9});
