Here is an example using both REGEXPREP and STRREP to replace double quotes with two single quotes:

>> mystr = 'Hello "Jonathan" ';

>> newStr1 = regexprep('Hello "Joe"','"','\''''') % single quote, backslash, 5 single quotes

newStr1 = 

           Hello 'Joe'

>> newStr2 = strrep('Hello "Joe"','"','''''') % 6 single quotes

newStr2 = 

           Hello 'Joe'
