MATLAB: How to find and replace tab or space characters

characterMATLABnonprintableregexprepreplacespacestrfindtab

I have a string, and I would like to find and replace the tabs and spaces with other characters. However, the STRFIND or STRREP functions don't seem to work.

The main method to replace tabs and spaces in MATLAB is to use regular expressions. Specifically, the REGEXPREP command is able to find tabs or spaces and replace them with any string. For example, to replace tabs with spaces in a string:

updatedString = regexprep(originalString, '\t', ' ');

strcat ignores trailing ASCII white space characters and omits all such characters from the output. White space characters in ASCII are space, newline, carriage return, tab, vertical tab, or form-feed characters, all of which return a true response from the MATLAB isspace function. Use the concatenation syntax [s1 s2 s3 ...] to preserve trailing spaces. strcat does not ignore inputs that are cell arrays of strings.
