Function Output selection help?

Hello Experts,

I have a function func. I know that func can give me [output1,output2] and by default gives me the output1.

How can I customize it and ask Matlab to give me the second output.

I will appreciate if you will give me the way to toggle between the outputs.

Thanks in advance.

If you define the function to give [output1,output2], then you can call the function

[~,output2] = func( )

and it will not output output1

[Wayne King]

when I say "call" I mean how you call the function at the command line:

>>[~,output2] = func(x); % for example

Thank you very much Wayne!

Simple and smart solution!

What is the technical name of the ~ sign?

What does it mean?

[Jan]

~ is either the not-operator, or in the case of inputs and outputs the command to ignore the argument.

This method does not work with Matlab versions before 2009b.

You've asked several very basic questions in the last 10 days. I suggest to read the Getting Started chapters in the documentation. If Google can answer a question, it is not efficient to ask in this forum

The technical name of "~" is "tilde". But of course, a pedant would point out that "~" as used in MATLAB is not correct, and that one should instead use "∼" (U+223C) TILDE OPERATOR, for logical negation, and possibly "⁓" (U+2053) SWUNG DASH, for indicating omission. And if you can tell the difference between those characters, you have better eyes than I do!
