strrep (MATLAB Function Reference)

String search and replace

str = strrep(str1,str2,str3)

Description

str = strrep(str1,str2,str3)

replaces all occurrences of the string str2 within string str1 with the string str3.

strrep(str1,str2,str3), when any of str1, str2, or str3 is a cell array of 
strings, returns a cell array the same size as str1, str2 and str3

obtained by performing a strrep using corresponding elements of the inputs. The inputs must all be the same size (or any can be a scalar cell). Any one of the strings can also be a character array with the right number of rows.

Examples

s1 = 'This is a good example.';
str = strrep(s1,'good','great')
str =
This is a great example.
