Description

This block transposes an MxN matrix to a NxM matrix. The result depends on rule parameter. When this parameter is equal to :

• 1 : the block outputs the transposed matrix.

• 2 : the block outputs the transposed matrix of the conjugate matrix.

The equivalent operators of this block in Scilab are y=u.' and y=u'. See quote (').

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.

• rule(1=.' 2=')

  Indicates the transposition rule. See the description for more information.

  Propriétés : Type 'vec' de taille 1.
