How to call a function with a char variable

Hello, Can someone help me with a small problem?

I stored my workspace as: s= whos() THe actual values are: s(1).name = A,s(2).name = B

 [X Y] = coordinates(A,B) works while 
[X Y] = coordinates(s(1).name, s(2).name,1); doesn't work?

How do I resolve this?

What is coordinates? Can you post an example?

Don't do this!!! Use save/load or some other form instead.

If you think you really, really must do this for some reason, then you're treading on thin ice -- read the info under eval to see why and alternatives for various programming paradigms. But, with the above caveat,

[X Y] = coordinates(eval(s(1).name), eval(s(2).name,1));

should, presuming that the variables in s(1:2) are appropriate inputs for the function or are indeed A and B after the execution of whos. But, who's to know that's really the case?

I don't understand why I shouldn't but it works! Thanks

Carry on down this road a while longer and I can assure you that you'll find out why... :)
