Description

This block outputs a sub matrix of the input matrix. The output matrix will be defining by using the parameters of this block.

Dialog box

• Datatype (1=real double 2=Complex)

  Type of the output matrix. It can be double or complex.

  Properties : Type 'vec' of size 1.

• Starting Row Index

  The first row of the submatrix.

  Properties : Type 'vec' of size 1.

• Ending Row Index

  The last row of the Submatrix.

  Properties : Type 'vec' of size 1.

• Starting Column Index

  The first column of the submatrix.

  Properties : Type 'vec' of size 1.

• Ending Column Index
