Difference between A' and A.'

What is the difference between A' and A.'? Bot seem to be the same..

>> A=1:4

A =

       1     2     3     4

>> A'

ans =

       1
       2
       3
       4

>> A.'

ans =

       1
       2
       3
       4

A.' is the transpose, and the A' is complex conjugate transpose. It only makes a difference if you have complex numbers in the matrix.

Matters in complex doamin, compare:

• A' : ctranpose()
• A.': tranpose()

An example:

A = rand(10);
isequal(A',A.') % 1

A = A*i;
isequal(A',A.') % 0

Does that mean they are the same for real number matrices and arrays?

[Oleg Komarov]

Yes.

thanks Oleg..
