Text Strings. MATLAB is wonderful with numbers. It deals with text but you can tell that its heart isn't in it. A variable in MATLAB is one of two types: numeric or string. A string matrix is like any other, except the elements in it are interpreted asASCII numbers. Thus the number 32 represents a space, the number 65 a capital A, etc.. A pattern defines rules for matching text with text-searching functions like contains, matches, and extract.You can build a pattern expression using pattern functions, operators, and literal text. For example, MATLAB ® release names, start with "R", followed by the four-digit year, and then either "a" or "b".Define a pattern to match the format of the release names:This MATLAB function extracts the substring that begins after the substring specified by pat and ends with the last character of str. ... If str is a string array or a cell array of character ... first create a pattern that matches a full path, and then extract what comes after that pattern.

Introduction to Cell to String MATLAB. There are two commands used to covet cell data into string format one is char and the other is a string. char and string commands extract all the data from cell arrays and stored in the form of string. In Matlab, we use string notations as data in single or double quotes ( " " or ' ' ).
