D. Triangular matrix
Answer:A
If the set of linear equations from the equationare expressed in matrix form, then what is the type of matrix obtained?
A. Symmetric matrix B. Skew symmetric matrix C. Toeplitz matrix D. Triangular matrix
Explanation: We observe that the matrix is not only symmetric but it also has the special property that all the elements along any diagonal are equal. Such a matrix is called a Toeplitz matrix and lends itself to efficient inversion by means of an algorithm.
