Sparse Matrix A sparse matrix is a large matrix with almost all elements of the same value (typically zero). The normal representation of a sparse matrix takes up lots of memory when the useful information can be captured with much less. A possible way to represent a sparse matrix is with a cell vector whose first element is a 2-element vector representing the size of the sparse matrix. The second element is a scalar speciflying the default value of the sparse matrix. Each successive element of the cell vector is a 3-element vector representing one element of the sparse matrix that has a value other than the default. The three elements are the row index, the column index and the actual value. Write a function called sparse2matrix that takes a singie input of a cell vector as defined above and returns the output argument called matrix, the matrix in its traditional form. Consider the folowing run: cellvec - {[2 3], e, [1 2 3], [2 2 -3]): matrix - sparsezmatrix(celivec) matrix - -3

Sparse Matrix
A sparse matrix is a large matrix with almost all elements of the same value (typically zero). The normal representation of a
sparse matrix takes up lots of memory when the useful information can be captured with much less. A possible way to
represent a sparse matrix is with a cell vector whose first element is a 2-element vector representing the size of the sparse
matrix. The second element is a scalar specifying the default value of the sparse matrix. Each successive element of the cell
vector is a 3-element vector representing one element of the sparse matrix that has a value olher than the default. The three
elements are the row index, the column index and the actual value. Write a funclion called sparse2matrix that takes a single
input of a cell vector as defined above and returns the output argument called matrix, the malrix in its traditional form.
Consider the following run:
cellvec-
{[2 31, e, [1 2 3], [2 2 -3]);
matrix = sparse2matrix(cellvec)
