search for: nargout

I am porting some MATLAB functions over to R and hopefully into a package, so I am curious if nargin and nargout work with R functions. Here is kind of an example of where I need to head in order to port "control-1.0.11" from Octave over to R. The Octave "control-1.0.11" package has the capability to produce bode plots of transfer functions. I hope to post this package once the port ove...

Hi all, How can I implement a multiple function return values scheme in a performance efficient way, just like what be done in Matlab or Octave?

Hi Yabin, Octave uses an octave_value_list object to return multiple values so I don't think it has anything to do with the compiler. A sample function that can be dynamically linked with Octave and called from octave interpreter: #include <octave/oct.h> DEFUN_DLD (divmult, args, nargout, "") { octave_value_list retval; // do some computation to compute r0 and r1 retval(0) = r0; retval(1) = r1; return retval; } Hamid > Hi all, > > How can I implement a multiple function return values scheme in a > performance efficient way, just like what be done in...

...# Create bigobject here if (return.value.assigned()) { bigobject } else { summary(bigobject) } } and x <- myfunction() # bigobject is assigned myfunction() # summary of bigobject is printed Octave and MATLAB have the nargout function that does what I want, and Perl has the wantarray function detecting the context in which a function is called. Perhaps match.call() can be made to do what I want, but, if so, I don't see it in reading the documentation. Sincerely, Paul Laub
