Description

extract columns

OP=0 or column, I is not connected

Y_vector = X[*,t]

In the evaluation cycle t (≥0), the column t of matrix X is copied to the output vector Y. The length of the output vector is equal to the number of input rows.

extract specified column

OP=0 or column, 0≤I<number of input columns

Y_vector = X[*,I]

In each evaluation cycle, the column I of matrix X is copied to the output vector Y. The length of the output vector is equal to the number of input rows.

extract rows

OP=1 or row, I is not connected

Y_vector = X[t,*]

In the evaluation cycle t (≥0), the row t of matrix X is copied to the output vector Y. The length of the output vector is equal to the number of input columns.

extract specified row

OP=1 or row, 0≤I<number of input rows

Y_vector = X[I,*]

In each evaluation cycle, the row I of matrix X is copied to the output vector Y. The length of the output vector is equal to the number of input columns.

transpose

OP=2 or transpose, I is not used

Y_matrix = X^T
