As an example if it is required to compare three values (a, b, c) and if a=b then out1 shall be 1.If b=c then out2 shall be 1. otherwise outputs shall be 0. How to write an s-function for something like that. How can I build an S function for more than one output and more than one input.

My plan is definitely to follow up with C S-Functions. I decided to highlight a few basic concepts using MATLAB S-Function because, in my opinion, it is easier to understand and debug. But I agree with you that C S-Functions offer a lot more possibility and will be useful for more users. @Ashish Sadanandan: Thank you for the comment.

IMHO, these articles would be a lot more interesting to read (and helpful) if you started writing about C S-Functions instead. Do you really have a lot of users that use M-file S-Functions?
