Array elements that are space characters
tf = isspace('str')
tf = isspace('str') returns an array the same size as 'str' containing logical 1 (true) where the elements of str are Unicode®-represented whitespace characters, and logical 0 (false) where they are not.
Whitespace characters for which isspace returns true include tab, line feed, vertical tab, form feed, carriage return, and space, in addition to a number of other Unicode characters. To see all characters for which isspace returns true, enter the following command, and then look up the returned decimal codes in a Unicode reference:
isspace(' Find spa ces ') Columns 1 through 13 1 1 0 0 0 0 1 0 0 0 1 0 0 Columns 14 through 15 0 1
