1. Suppose A is a 967 × 80 matrix. Use the matrix notations discussed in class to create the following.
(a) Write notation for a matrix B that consists of columns 15,21 and 77 of A.
(b) Write notation for a matrix C that consists of rows 22,37, 300 and 457 of A.
(c) Using the matrix C from the previous part, write notation in terms of the entries in A for a matrix H that consists of entries in C that are in either column 35 or column 76 in matrix C.
