# MULT

## Summary

Element-wise multiplication of two input series. Produces outReal[i] = inReal0[i] * inReal1[i].

## Formula

outReal[i] = inReal0[i] * inReal1[i]

## Inputs

- `inReal0` — First operand series
- `inReal1` — Second operand series

## Outputs

- `outReal` — Product of the two inputs at each index
