I have code that uses ishift(Kr1')' What is the function of the single quotes?

Here is a sample of the code:

Kr(1:2:M,2:2:N)=(Kr0+shift1(Kr0)+Kr1+ishift1(Kr1')')/4;

The Krx are matrices and the shift is a function to shift either left or write. I have run this code with and without the single quotes and it gives different answers but I can't understand what the ')' is doing?

This line

ishift1(Kr1')'

Can be written as

a=Kr1'  % Conjugate transpose of Kr1
b=ishift(a)' % transpose of ishift(a)

Example

k=[1 2 3];
out=sin(k')'

Thanks. I didn't know that ' was transpose. Chris
