Initialize an array, say A, to store the non-zero elements of the matrix.

Index of matrix element at position (i, j) = (N * (j – 1) – ((j – 2) * (j – 1))/2) + (i – j)įollow the steps below to solve the problem:

In this method, consecutive elements of a column are placed adjacently in the array.

Index of matrix element at position (i, j) = ((i * (i – 1))/2 + j – 1)

The following formula is used to find out the respective positions of the non-zero elements of the lower triangular matrix in the 1-dimensional array.

In this method, adjacent elements of a row are placed next to each other in the array.
