Matrix Algebra and Transformations
摘要
Our aim is not to provide a comprehensive study of linear algebra, but rather to focus on the essential aspects of matrix algebraMatrix algebra [1] used in DF algorithmsDF algorithms. We will also address some numerical considerations. This chapter will cover topics such as matrix algebraMatrix algebra, digital filtersDigital filter, the discreteFourier transform Fourier TransformDiscrete Fourier Transform (DFT), and its extensions, all of which are relevant to DOA applications. Additionally, we will provide access to the C code for all the functions. We aim to minimize the need for the reader to consult additional books, except for specific details that may require further reference.
