Description

This block outputs a sub matrix of the input matrix. The dimensions of the input matrix are specified in the Input Dimension parameter. The user gives the range of extraction with four parameters:

• The parameters Starting Row Index and Ending Row Index specify the lines range to be extracted.
• The parameters Starting Column Index and Ending Column Index specify the column range to be extracted.

Dialog box

• Datatype (1=real double 2=Complex) It indicates the 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.
• Starting Row Index The first row of the sub-matrix. Properties : Type ‘vec’ of size 1.
• Ending Row Index The last row of the sub-matrix. Properties : Type ‘vec’ of size 1.
• Starting Column Index The first column of the sub-matrix. Properties : Type ‘vec’ of size 1.
• Ending Column Index The last column of the sub-matrix. Properties : Type ‘vec’ of size 1.
• Input Dimension The Matrix input dimensions. Properties : Type ‘vec’ of size 2.
