Introduction:

A square matrix is referred to as a triangular matrix if all of the components below and/or above the diagonal are zeros. Most triangular matrices fall into one of two categories.

  • Lower triangular matrices are square matrices that have zero values for every element above the primary diagonal.
  • An upper triangular matrix is a square matrix that has zero values for every element below the principal diagonal.
