I still can't find a book with properties and theorems involving block matrices multiplication to reference in my undergraduate work.
thanks

A block matrix is a matrix that is divided into smaller matrices or "blocks" which are arranged in a rectangular grid. This allows for easier manipulation and calculation of matrices with large dimensions.
Block matrix multiplication is a method of multiplying two block matrices together. It involves multiplying the individual blocks of the matrices and then arranging them in a new block matrix according to certain rules.
Block matrix multiplication is different from regular matrix multiplication because it involves breaking down the matrices into smaller blocks and then performing the multiplication on these smaller blocks. This method is more efficient for larger matrices as it reduces the number of computations required.
There are several benefits of using block matrix multiplication. It allows for easier manipulation of large matrices, reduces the computational complexity of matrix multiplication, and can be easily parallelized for faster computation. It is also useful in various applications such as signal processing, image processing, and optimization problems.
Yes, there are certain rules and properties that must be followed when performing block matrix multiplication. For example, the dimensions of the individual blocks must be compatible for multiplication, the order of the blocks matters, and there are special rules for multiplying diagonal blocks. It is important to understand these rules and properties in order to accurately perform block matrix multiplication.
