How to replace string in a line that matches a regular expression and write it to a file in MATLAB R2024b?

In my workflow, I would like to find a match in a string based on a regular expression (pattern) and replace that with suitable text. Next, I would like to write that text to a file. How can I accomplish that in MATLAB R2024b?

The workflow you described is easily achievable in MATLAB R2024b using two built-in functions - "regexprep" and "writelines". For the first part of your workflow, you can use "regexprep" to find and replace characters in a string that match the requested pattern. Check examples for replacing text with "regexprep" for some examples on how you can do that. Next, you can use "writelines" to write a given string into a file. You can refer to the "writelines" documentation for more information and examples.
