VECTOR_INSERT

The VECTOR_INSERT node inserts a value to the Vector at the specified index. Inputs ------ v : Vector The input vector to insert value. Params: element : int The value to add to the input vector. index : int The index of the vector to insert value. Returns: out : Vector The new vector that contains the inserted value

In this example, we generate a vector by using a LINSPACE node. Then, a value specified (13) is inserted at index 0 VECTOR_INSERT. The value is visualized with SCATTER node. Another set of example excluding VECTOR_INSERT node has been added for comparison.
