Help about Octave Fmldivide function in C++

[Jeremy Yan]

Dear Sir/Madam,

I am trying to solve a linear equation Ax=b in C++ program by calling Octave function mldivide. I know in Octave software command window, I just need to type x=mldivide(A,b). Then I read your instruction on Octave website (http://octave.sourceforge.net/doxygen/html/d4/d05/data_8cc.html#acf094020d4951303dfc5df0055f0ef36) about how to use Fmldivide function. Here is the declaration of Fmldivide: 

octave_value_list Fmldivide

(

const octave_value_list &

args, int) .

What  "args" should I use? Since I have the matrix A and the vector b two args. What does the "int" mean? 

Thank you so much in advance!

Best,

Jeremy
