Function exec_op_on_tensors 

pub fn exec_op_on_tensors<B: TensorBackend>(
    op: &StdTensorOp,
    inputs: &[&Tensor],
    backend: &mut B,
) -> Result<Vec<Tensor>>

Execute a single StdTensorOp on concrete tensors.

Most ops produce one output tensor. Multi-output linalg ops return one tensor per output slot.
