6.18.1

Consider the sparse matrix X below and write C code that would store this code in Yale Sparse Matrix Format.

Row 1 [1, 2, 0, 0, 0, 0]

Row 2 [0, 0, 1, 1, 0, 0]

Row 3 [0, 0, 0, 0, 9, 0]

Row 4 [2, 0, 0, 0, 0, 2]

Row 5 [0, 0, 3, 3, 0, 7]

Row 6 [1, 3, 0, 0, 0, 1]

6.18.2

In terms of storage space, assuming that each element in matrix X is single-precision floating point, compute the amount of storage used to store the matrix above in Yale Sparse Matrix Format.
