Description

This Block transposes an MxN matrix to a NxM matrix. For complex data type it uses the hermitian transpose. The equivalent of this block in Scilab is y=u'.

Dialog box

  • Datatype(1=real double 2=Complex)

    It indicates the data type of the output. It support only the two types double (1) and complex (2). If we input another entry in this label xcos will print the message "Datatype is not supported".

    Properties : Type 'vec' of size 1.

Example

 
.                        Complex

| 1+i   2+3i    3+2i |   Tranpose    | 1- i   4- i |
| 4+i   5-8i    6-2i | ----------->  | 2-3i   5+8i |
--                  --               | 3-2i   6+2i |
.                                    --           --
