प्रश्न

Classify the following matrix as, a row, a column, a square, a diagonal, a scalar, a unit, an upper triangular, a lower triangular, a symmetric or a skew-symmetric matrix:

`[(2, 0, 0),(3, -1, 0),(-7, 3, 1)]`

उत्तर

Let A = `[(2, 0, 0),(3, -1, 0),(-7, 3, 1)]`

As every element above the diagonal is zero in matrix A.

∴ A is a lower triangular matrix.
