If the size of the strings match, we can concatenate vertically and horizontally just like numeric matrices. Or, parse a number from a string with str2num() A = num2str() %Takes an optional formatting string - see Formatting Strings section We can also use the num2str() and mat2str() functions to generate string representations of numeric matrices. The num2xxx and xxx2num functions operate on signed numbers.
We can convert from string representations of hexadecimal or binary numbers to decimal numbers and back using the dec2hex(), hex2dec(), dec2bin(), and bin2dec() functions. The char() and abs() functions convert from integers to the ascii equivalents and vice versa.

Type doc isstrprop for the full list.Ī = isstrprop(str, 'punct') % punctuationī = isstrprop(str, 'alphanum') % alpha or numeric charactersĬ = isstrprop(str, 'digit') % decimal digitsĭ = isstrprop( '3A', 'xdigit') % valid hexadecimal digits str = The isstrprop() function can be used much like the isletter() or isspace() functions, allowing you to test which characters in a matrix belong to one of several different categories. K = deblank(A) % trim trailing blank spaces only. J = strtrim(A) % trim leading and trailing blank spaces.
G = isspace(A(1:6)) % which characters are spaces? - returns a logical array A = ' This is Test String #1! 'ī = A(1:5) % extract the first 5 charactersĭ = repmat( % replicate char arrays, just like numeric onesĮ = 'z':-1: 'a' % create the matrices just like numeric ones.į = isletter(A(1:6)) % which characters are letters? - returns a logical array Strings in Matlab are actually character matrices, which can be manipulated in very similar ways to numeric matrices.
