  • Get real! Solving a complex-value linear system using real arithmetic

    Consider a linear system of complex-valued equations of the kind , where are complex square and rectangular matrices, respectively, and is the unknown complex matrix. To compute , a natural option is to use any algorithm available in the literature initially conceived for real systems, such as Gauss elimination, LU/Cholesky decomposition, and translate its operations to complex arithmetic. However, there may…
