The functions listed in this table provide a number of ways to convert character strings to numeric data. Function. Description. Example. uintN (e.g., uint8). Convert a character to an integer code that represents that character. 'Hi' â 72 105. str2num. Convert a character type to a numeric type.'72 105' â [72 105]. str2double. Similar to str2num, but offers better performance and works with cell arrays of strings.onvert a character to an integer code that represents that character. 'Hi' â 72 105. str2num.
