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 https://en.wikipedia.org/wiki/Conjugate_transpose#Definition 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:
A=[6,-2,-1,0;3,-5,0,-3;10,5,0,-1;-1,3,4,1];
B=A*A';
disp(B)
You can verify that
C=A'*A
gives the same result.
