In addtion, when I compile the source code without the header file string.h, Mathematica gives me a correct DLL file. Very odd!

The Visual Studio gives the suggestion memory.h, while when I google the keyword memcpy, I found that the corresponding header file is string.h. Any suggestion?

Hi, everyone. Did someone know which header file I should add when using C fucntionmemcpy()?

@Szabolcs Hi, I would like to ask you a question about the C function refactor. Rencently, I wrote two similar C functions wrapper called BSplineCurveKnotsRemoveAll[] and BSplineSurfaceKnotsRemoveAll[] for curve and surface, respectively. I would like to merge them to a C function BSplineKnotsRemoveAll[], any suggestion? About the detail, please see the following question. Thanks:)

@Szabolcs Hi, I have applied your method to my package to return the second result. Thanks a lot :) Please see the below snapshot.

My university library only buy the journal after 1996.

Hi, guys!I wanna know could someone download this papaer?

Does Mathematica 11 using the new programming font?

Hi, everyone, today I encountered a problem when using RegionDifference[].

@JasonB THX, I change the url to end with "dl=1", but I got same error:) Maybe In China I cannot use the Dropbox.

@Pickett I cannot open the address in the browser, because I cannot use that Dropbox site in China:(. I uploaded that files via happy fish's help.

Could someone help me test the following code?

Guys! Good afternoon:)

@halirutan According to my experience, the sampling strategy ParametricPlot3D[] and BSplineSurface[] is different.

@halirutan Your method is very like built-in. Thanks:). In addtion, I have tested J.M. 's method just now, I think it is a little time-consuming.

@J.M. Please see this comment

@J.M. I tried the primitive style EdgeForm[Blue], which given me the following result:

Hi, guys. Did someone know how to remove the mesh of the following graphic?

Hello, everyone. Did someone know how to achieve the data of the following classical model?

@J.M. Hi, J.M., I sent an email to you just now.

I use the MinGW compiler owing to that the Visual Studio 2012 compiler cannot compile the right code.

Hi, guys! Good evening:) Did someone know how to call the MinGW compiler when using CreateLibrary[] ?

@Szabolcs Thanks. In general, I know the function declaration is written in a separate *.h file.

I know putting struct first, then function declaration could deal with it, but obviously which is not a good solution.

Hello, everyone, I would like to how to deal with the following question? Thanks!

@kirma I think it is very useful for me to learn C, because I have learnt the basic mathematical theoy, such as advanced mathematics, numerical analysis, etc.

@kirma Got it. Thanks a lot for your help.:)

@kirma The main compiler in my laptop is MinGW, howeverm I cannot find the math.cfile via windows search operation.

@DanPantry @Pimgd Oh, I am sorry:)
