What are advantages of a sparse matrix?
Using sparse matrices to store data that contains a large number of zero-valued elements can both save a significant amount of memory and speed up the processing of that data. sparse is an attribute that you can assign to any two-dimensional MATLAB matrix that is composed of double or logical elements.The sparse attribute allows MATLAB to:Store only the nonzero elements of the matrix, together with their indices.Reduce computation time by eliminating operations on zero elements.For full matrices, MATLAB stores every matrix element internally. Zero-valued elements require the same amount of storage space as any other matrix element. For sparse matrices, however, MATLAB stores only the nonzero elements and their indices. For large matrices with a high percentage of zero-valued elements, this scheme significantly reduces the amount of memory required for data storage.
What is the comparative form of sparse?
The comparative form of sparse is sparser
What type of matrix is a vector?
Vector matrix has both size and direction. There are different types of matrix namely the scalar matrix, the symmetric matrix, the square matrix and the column matrix.
Is matrix polynomial and polynomial matrix same?
No. A matrix polynomial is an algebraic expression in which the variable is a matrix. A polynomial matrix is a matrix in which each element is a polynomial.

What is a sparse matrix?
A sparse matrix is a matrix in which most of the elements are zero.
What is transpose of the sparse matrix?
Another sparse matrix.
How to identify Sparse matrix?
A sparse matrix is one which normally contains a large proportion of elements whose value is 0. There is no exact proportion at which a matrix becomes sparse.

What are disadvantages of sparse matrix in data structure using c?
what is the disadvantage of sparse matrix?
What are sparse matrixes?
A sparse matrix is an array with more zero values than non-zero values.
What is a sparse matrix in c programming?
Sparse matirx can be represented 1-dimensionally, by creating a array of structures, that have members sumc as: Struct RM{int ROW,int COL, int non_zero}; struct RM SM[Number_non_Zeros +1]; then input row,col for each non-zero element of the sparse matrix. if still unclear please fell free to requestion or query on ikit.bbsr@gmail.com, specifying clearly the question in the subject.

How is sparse matrix stored in the memory of a computer?
A sparse matrix contains many (often mostly) zero entries. The basic idea when storing sparse matrices is to only store the non-zero entries as opposed to storing all entries. Depending on the number and distribution of the non-zero entries, different data structures can be used and yield huge savings in memory when compared to a naïve approach. One example of such a sparse matrix format is the (old) Yale Sparse Matrix Format [1]. It stores an initial sparse N×N matrix M in row form using three arrays, A, IA, JA. NZ denotes the number of nonzero entries in matrix M. The array Athen is of length NZ and holds all nonzero entries of M. The array IA stores at IA(i) the position of the first element of row i in the sparse array A. The length of row i is determined by IA(i+1) - IA(i). Therefore IA needs to be of length N + 1. In array JA, the column index of the element A(j) is stored. JA is of length NZ. Another possibility is to use quadtrees
What is sparse array?
A sparse array (or sparse matrix) is an array where only a few elements are actually allocated storage space in memory, the unallocated elements are forced to zero for calculation purposes. Such arrays usually use pointers to reference the storage for the allocated elements.
