The string in MATLAB software consists of any number of characters and is contained in the single quotes. Actually, strings are considered as vectors in which each and every element is a single character that means that many of the vector operations and functions which we have seen already work with the strings. The MATLAB also has numerous built-in functions that are written particularly to manipulate the strings.
In several cases, the strings contain numbers, and it is helpful to convert from strings to numbers and vice versa; the MATLAB also has the functions to do this.
There are numerous applications for using the strings, even in fields that are predominantly numerical. For illustration, whenever data files consist of combinations of the numbers and characters, it is often essential to read each line from the file as a string, split the string into pieces, and convert the parts which contain numbers to number variables which can be used in calculations.
