Special matrix operations.
[SPU ACNV X OP I OUT Y]
| In: | X | input matrix |
|---|---|---|
| OP | a number or string; selects operation to be performed | |
| I | optional row or column index | |
| Out: | Y | vector or matrix; depends on OP and I |
- Description
-
- extract columns
- OP=
0orcolumn, I is not connected- Yvector = 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,.
