Same as dot but handle single row matrix differently by multiplying each value but not sum them up

1 | ```
dot.ext(x, y, mydim)
``` |

`x` |
numeric vector or matrix |

`y` |
numeric vector or matrix |

`mydim` |
Elementwise product (if 1); otherwise defined by |

Returns the 'dot' or 'scalar' product of vectors or columns of matrices. Two vectors must be of same length, two matrices must be of the same size. If x and y are column or row vectors, their dot product will be computed IF mydim is 1 (only difference from `dot`

).

A scalar or vector of length the number of columns of x and y.
