Transpose vector or matrix

Syntax

Description

B = [A](#buaszto-A).' returns the nonconjugate transpose of A, that is, interchanges the row and column index for each element. If A contains complex elements, thenA.' does not affect the sign of the imaginary parts. For example, if A(3,2) is 1+2i and B = A.', then the element B(2,3) is also1+2i.

example

B = transpose([A](#buaszto-A)) is an alternate way to execute A.' and enables operator overloading for classes.

Examples

collapse all

Create a matrix of real numbers and compute its transpose. B has the same elements as A, but the rows of B are the columns of A and the columns of B are the rows of A.

A = 4×4

16     2     3    13
 5    11    10     8
 9     7     6    12
 4    14    15     1

B = 4×4

16     5     9     4
 2    11     7    14
 3    10     6    15
13     8    12     1

Create a matrix containing complex elements and compute its nonconjugate transpose. B contains the same elements as A, except the rows and columns are interchanged. The signs of the imaginary parts are unchanged.

A = [1 3 4-1i 2+2i; 0+1i 1-1i 5 6-1i]

A = 2×4 complex

1.0000 + 0.0000i 3.0000 + 0.0000i 4.0000 - 1.0000i 2.0000 + 2.0000i 0.0000 + 1.0000i 1.0000 - 1.0000i 5.0000 + 0.0000i 6.0000 - 1.0000i

B = 4×2 complex

1.0000 + 0.0000i 0.0000 + 1.0000i 3.0000 + 0.0000i 1.0000 - 1.0000i 4.0000 - 1.0000i 5.0000 + 0.0000i 2.0000 + 2.0000i 6.0000 - 1.0000i

Input Arguments

collapse all

Input array, specified as a vector or matrix.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | logical | char | string | struct | cell | categorical | datetime | duration | calendarDuration
Complex Number Support: Yes

Tips

• The complex conjugate transpose operator, A', also negates the sign of the imaginary part of the complex elements inA.

Extended Capabilities

expand all

The transpose function fully supports GPU arrays. To run the function on a GPU, specify the input data as a gpuArray (Parallel Computing Toolbox). For more information, see Run MATLAB Functions on a GPU (Parallel Computing Toolbox).
