1, is the first to establish the M file matlab.
Ellipsefit.m
It contains: function [Xc,yc,a,b,phi,p]=ellipsefit (x, y)
2.MCC command compilation generated by H, DLL, lib and other files
In the MATLAB command line, enter:
mcc-w cpplib:ellipsefit ellipsefit.m-t link:lib (this mode is C + + style function)
(The specific command meaning can be referred to "proficient in MATLAB and C + + mixed Programming" Liouville, 3rd edition, Beijing University of Aeronautics and Astronautics Press. )
(Ellipsefit is the generated LIB file name, which can be arbitrarily named.) ELLIPSEFIT.M is the. m file name that you want to invoke.
At this point, you can see that a series of files are generated in the directory where ELLIPSEFIT.M is located. We will use:ellipsefit.h, Ellipsefit.dll, Ellipsefit.lib
2.3: Create a VC project: Test
For simplicity, we are building a Win32 console program here. As follows:
Then, put the above 3 files (ellipsefit.h, Ellipsefit.dll, Ellipsefit.lib
) to the directory in which the VC works, so that the VC can call it and add the. h file to the project.
Among them, the ellipsefit.h中的function [Xc,Yc,A,B,Phi,P]=ellipsefit(x,y) corresponding C + + style of the function interface is:

externvoid MW_CALL_CONV ellipsefit(intconstconst mwArray& y);

That is, call the interface in your own main program, using the Mwarray matrix for data manipulation in C + +
