Question

If A is a matrix of order m*n,then P(A) is a)m b)n c) =min(m,n)

Answer 1

Answer:

according to me

Step-by-step explanation:

option a) m

Answer 2

Answer:

The Correct Option is C) P(A) = min of (m, n)

Step-by-step explanation:

The Largest number of straight independent rows in a matrix A is called as row rank of A, and the maximum number of linearly independent columns in a matrix A is called the column rank of A.

If A is an m by n matrix, that is, if A has m rows and n columns, then it will be equal to the..

row rank of A lesser or equal to m

column rank of A lesser or equal to

Sometimesin a matrix we have like

the row rank of A = the column rank of A

Because of this fact, there is no reason to differentiate between the row rank and the column rank; the regular value is simply called the rank of the matrix. Therefore, if A is m x n, it follows from the inequalities in (*) that

rank (Am×n) Lesser of equal to min(m, n)

where min( m, n) denotes the smaller of the two numbers m and n (or their common value if m = n). For example, the rank of a 2×4 matrix can not be more than 2, and the rank of a 4 x 2 matrix can not be more than 2.
