I would like to print a string containing the '%' character. However, when I attempt the following:
sprintf('100%')
The output reads:
100

To escape the percent symbol, use two percent signs. For example:
sprintf('100%%')
Yields the output:
100%

str2write = '% whatever 75% ';
str2write = regexprep( str2write, '%', '%%' );
or
str2write = '% whatever 75% ';
str2write = strrep( str2write, '%', '%%' );

sprintf('%s', '100%')
The % are only "eaten" if they occur in the first parameter, the format position.
