Given: A \: is \: 2\times3 matrix and B is matrix such that A^{T}B\: and \: BA^{T}both are defined then what is order of B

Solution:

A \: is \: 2\times3 matrix

So,

A^{T} is 3\times 2 matrix

Here, A^{T}B  is exist

=A^{T} _{3\times2}\: B_{m\times n}

So,m=2 in B

Here BA^{T} is exist

=B_{2\times n}\: A^{T}_{3\times 2}
