Which algorithm eig () function use ?

Which algorithm eig () function use ?

I have to impliment on FPGA , can how can i find eig whithout using matlab functions , or very less

Answer 1

Which version of Matlab do you mean?

There are e.g. differences between Matlab 7.1 and Matlab 7.9. And even the same Matlab version produces slightly different results on different platforms.

Answer 2

Good question.

I always thought the default eigenvalue algorithm was the QR algorithm ( http://people.inf.ethz.ch/arbenz/ewp/Lnotes/chapter3.pdf ), but this is just a guess...

Answer 3

[Abdullah Khan]

Any version , gotta implement the ago on FPGA

Thanks

Do I understand correctly, that your question does not concern Matlab's eig() function, but that you are searching for a general algorithm? Then asking WikiPedia might be a better idea than a Matlab forum.

can u plz tell me which algo has been used for eig() in matlab 2014a and 2018b?

There are different algorithms for solving eigenvalue problems, depending on the properties of the inputs. The most well-known standard library for linear algebra operations is LAPACK, which is open source. Here is a reference page on solving eigenvalue problems from LAPACK:

https://www.netlib.org/lapack/lug/node37.html

and here's a list of some LAPACK functions related to solving the eigenvalue problem:

If you need MATLAB code that calls EIG to be translated to C code, you could also look at MATLAB Coder, which will generate C code to solve, for example, an eigenvalue problem if EIG is used.
