[NEW ALGORITHM] Sparse matrix Algorithms

[Salini-sat]

Description:

I want to add sparse matrix operations like creation of sparse matrix , it's representation and it's operations such as, addition and multiplication of two sparse matrixes .

Checklist:

• I'm a Contributor in GSSoC-ext
• I Want to work on it

Additional Information:

A matrix is a two-dimensional data object made of m rows and n columns, therefore having total m x n values. If most of the elements of the matrix have 0 value, then it is called a sparse matrix.

Why to use Sparse Matrix instead of simple matrix ?

Storage: There are lesser non-zero elements than zeros and thus lesser memory can be used to store only those elements. Computing time: Computing time can be saved by logically designing a data structure traversing only non-zero elements..
