Sparse Matrix is a special kind of matrix. In this matrix many of the elements are not important. They are equal to zero. Non- important elements do not require to be processed. Yes, Sparse Matrix is considered lightly. It is just given a passing reference. Empty operations are performed on Sparse Matrix elements because such elements are insignificant. Criterion: I have assumed that if the number of zeros in a matrix are more than the 'result' obtained after dividing the total number of matrix elements by two, then the matrix is a Sparse Matrix. ______________________________ ______________________________ Sparse Matrix Specifications: _____________________________ _____________________________ 1 ) No. of rows = m 2 ) No. of columns = n 3 ) No. of elements = m × n 4 ) Enter matrix elements one by one 5 ) Half No. of elements hn = (m × n)/2 6 ) No. of zeroes = nz 7 )if ( nz >= hn ) Display 'Sparse Matrix' else Display 'Not a Sparse Matrix' 8)...
