How to merge two real matrices into a complex matrix by python

This article introduces the relevant knowledge of "how python merges two real matrices into a complex matrix". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Problem description:

Sometimes it is necessary to merge two real matrices, one as the real part and the other as the imaginary part, into a complex matrix.

Solution:

If you are merging on the second dimension (real: Data [:, 0,:] imag: Data [:, 1,:]), there are two ways

The first, result = Data [:, 0,:] + 1j*Data [:, 1,::] the second, result = 1j*Data [:, 1,:] result + = Data [:, 0,:,:]

The second method saves more memory.

This is the end of how python merges two real matrices into a complex matrix. Thank you for your reading. If you want to know more about the industry, you can follow the website, the editor will output more high-quality practical articles for you!
