pagectranspose

Page-wise complex conjugate transpose

Syntax

Y = pagectranspose(X)

Description

Y = pagectranspose(X) applies the complex conjugate transpose to each page of N-D array X. Each page of the output Y(:,:,i) is the conjugate transpose of the corresponding page in X, as in X(:,:,i)'.

Examples

Transpose Pages of Complex N-D Array

Create a 3-D complex array A, and then use pagectranspose to find the complex conjugate transpose of each page of the array.

r = repelem(1:3,3,1);
A = cat(3,r,2*r,3*r);
A = A + 1i

A = 
A(:,:,1) =

   1.0000 + 1.0000i   2.0000 + 1.0000i   3.0000 + 1.0000i
   1.0000 + 1.0000i   2.0000 + 1.0000i   3.0000 + 1.0000i
   1.0000 + 1.0000i   2.0000 + 1.0000i   3.0000 + 1.0000i


A(:,:,2) =

   2.0000 + 1.0000i   4.0000 + 1.0000i   6.0000 + 1.0000i
   2.0000 + 1.0000i   4.0000 + 1.0000i   6.0000 + 1.0000i
   2.0000 + 1.0000i   4.0000 + 1.0000i   6.0000 + 1.0000i


A(:,:,3) =

   3.0000 + 1.0000i   6.0000 + 1.0000i   9.0000 + 1.0000i
   3.0000 + 1.0000i   6.0000 + 1.0000i   9.0000 + 1.0000i
   3.0000 + 1.0000i   6.0000 + 1.0000i   9.0000 + 1.0000i

B = pagectranspose(A)

B = 
B(:,:,1) =

   1.0000 - 1.0000i   1.0000 - 1.0000i   1.0000 - 1.0000i
   2.0000 - 1.0000i   2.0000 - 1.0000i   2.0000 - 1.0000i
   3.0000 - 1.0000i   3.0000 - 1.0000i   3.0000 - 1.0000i


B(:,:,2) =

   2.0000 - 1.0000i   2.0000 - 1.0000i   2.0000 - 1.0000i
   4.0000 - 1.0000i   4.0000 - 1.0000i   4.0000 - 1.0000i
   6.0000 - 1.0000i   6.0000 - 1.0000i   6.0000 - 1.0000i


B(:,:,3) =

   3.0000 - 1.0000i   3.0000 - 1.0000i   3.0000 - 1.0000i
   6.0000 - 1.0000i   6.0000 - 1.0000i   6.0000 - 1.0000i
   9.0000 - 1.0000i   9.0000 - 1.0000i   9.0000 - 1.0000i

Input Arguments

X — Input array

Tips

• The page-wise complex conjugate transpose is equivalent to permuting the first two dimensions of the array with permute(conj(X),[2 1 3:ndims(X)]).
