Question

find rank by using triangular form​

Answer 1

Step-by-step explanation:

If A is the upper triangular matrix of order n, given below, is it possible to work out, (or at least bound) its rank?

A=⎡⎣⎢⎢⎢⎢⎢⎢⎢⎢⎢⎢000⋮0010000⋮00⋆⋆203⋮00………⋱……⋆⋆⋆⋆⋆0⋆⋆⋆⋆⋆⋆⎤⎦⎥⎥⎥⎥⎥⎥⎥⎥⎥⎥

Where each ⋆ represents any number (not necessarily the same) from C.
