# Notation: Matrix with a prime

I can't find this over the Internet: what does a matrix with a prime mean?

A'


I found this in an exercise, this is in basic linear algebra.

Look through your text. It might mean another matrix, or it could mean the transpose. The notation is not standard. So your textbook author has something specific in mind. – Scott Carter Oct 9 '12 at 18:25
It really is quite contextual. Sometimes $A^{\prime}$ is taken to mean the transpose of the matrix. – EuYu Oct 9 '12 at 18:25
It could also just denote another matrix, or it could be denoting a change of basis making a matrix from A to A'. – rschwieb Oct 9 '12 at 18:29
If you state the exercise, it will probably make the meaning evident. – hardmath Oct 9 '12 at 18:36

In Matlab, this means adjoint or hermitian conjugate: $A^\dagger$
