Description

This Block transposes an MxN matrix yielding an NxM matrix. For complex data type it uses the hermitian transpose. The equivalent of this block in Scilab is the prime operator.

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 Scicos 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 |
.                                    --           --
.                  Real 
--          --               --      --
| 1   -2   3 |   Tranpose    | 1    4 |
| 4   5    6 | ----------->  |- 2   5 |
