Theories on matrices and complex numbers
WebbHere c–di and a+bi are the 1 × 2 range representations of the corresponding complex number. Note that CReal, CImag, CAbs, CConj and CText are ordinary functions, while the others are array functions. A constant complex number can be represented in the form {a, b}.Thus the complex number 3–4i can be represented by {3,-4}. The complex number i … Webb19 jan. 2024 · As was already mentioned in Chap. 1, complex numbers may appear as matrix elements.Moreover, the characteristics of real matrices (such as eigenvalues, see Chap. 5 “Vector Spaces” on page 226) in some cases appear to be complex. In this connection, let us discuss the methods of algebra of complex numbers.
