VECTOR_INDEXING

The VECTOR_INDEXING node returns the value of the vector at the requested index. Inputs ------ v : vector The input vector to index. Params: index : int The index of the vector to return. Returns: out : Scalar The scalar index of the input vector.

Python Code

from flojoy import flojoy, Vector, Scalar

In this example, we generate a vector by using a LINSPACE node. Then, the value at index 100 is extracted at using VECTOR_INDEXING. The value is visualized with BIG_NUMBER.
