Apply boundary condition (upper and lower limit) to parameters during the fitting using the function nlinfit?

Does anyone knows how to apply boundary condition to the parameters during the fitting using the function nlinfit?

I know that this could be done using the function fit, but i need to use the function nlinfit. (in that regards see the post in the link attached)

Thank you very much in advance for the help.
