WebNote that the common factor 5 has been taken out and placed in front of the brackets. The expression inside the brackets is obtained by dividing each term by 5. In general: To factorise an algebraic expression, take out the highest common factor and place it in front of the brackets. Then the expression inside the brackets is obtained by ... WebStoring a sparse matrix. A matrix is typically stored as a two-dimensional array. Each entry in the array represents an element a i,j of the matrix and is accessed by the two indices i and j.Conventionally, i is the row index, numbered from top to bottom, and j is the column index, numbered from left to right.
