"Multiplier" is like "Compose", but with multiplication instead of function application. Otherwise the code is identical except for the argument types (numbers instead of functions). |

<lang>multiplier(n1,n2)={ |

x -> n1 * n2 * x |
|||
}; |
|||
test()={ |

my(x = 2.0, xi = 0.5, y = 4.0, yi = 0.25, z = x + y, zi = 1.0 / ( x + y )); |
|||
print(multiplier(x,xi)(0.5)); |
|||
print(multiplier(y,yi)(0.5)); |
|||
print(multiplier(z,zi)(0.5)); |

};</lang> |

The two are very similar, though as requested the test numbers are in 6 variables instead of two vectors. |
