To expand on Ravi's answer:
When using Linear Algebra,
(better) or (not recommended) is the non-conjugate transpose of the matrix A.
(more common) or (used in some fields) is the conjugate transpose of the matrix A. See also which contains some less used symbols for this.
is the inverse of the matrix A
in Linear Algebra is more likely to refer to either a distinguished version of A (such as after applying a transformation matrix to A), or else to the derivative of A -- but it is not uncommon for ' to be used for either transpose or conjugate transpose in programming languages.

For a real matrix, A' is Matlab code for the transpose of A. Therefore:
41 28 50 -16 28 43 8 -21 50 8 126 4 -16 -21 4 27
You can verify that
gives the same result.

A'*A gives the same result only if A is square.
