Any comment made here is solely my opinion and owned by me. Mathworks is not responsible for whatever I say. Hence it would be perfectly fine when other community members give a better opinion as they might be a subject matter expert for that issue.
Feel free to add your comments to add some knowledge to a discussion or for correcting me whenever i might seem wrong.
