Know Formula used in function Matlab

Good morning everyone!

I'm developing C++ software for my project using 3d accelerometer/gyroscope MPU6050, and I would like to know the formula used by Matlab for a general function__, let's say the " source code" that explain the math behind the objects functions, for example the function interp3

Of course the same is for other functions used.

Thank you very much for your attention! Have a nice day, FC

Many of the functions in MATLAB are implemented as MATLAB function files. For those, you can read the code. The interp3 function falls into this category.

For built-in functions like fft or sin, we don't distribute the source code. If you want to see how those functions are implemented, your first step is to go here.

Thanks Steven for your kind reply!

Let's say that I'm more interested in advanced functions such as _interp3, how is it possible to access to those files you are talking about?

For me it's just important the math, since later I have_to develop them in C++ by myself.

Thanks! FC

If they are implemented as a MATLAB function, you can edit them. Just be careful not to modify them.

Depending what you're trying to do and what functions you need to use, you might find the MATLAB Coder product useful to generate code. The documentation indicates interp3 is supported for code generation, though the end of the interp3 documentation page lists some limitations.
