### MULT

Multiplies two NDF data structures

#### Description:

The routine multiplies two NDF  data structures pixel-by-pixel to produce a new NDF.

mult in1 in2 out

#### Parameters:

First NDF to be multiplied.
Second NDF to be multiplied.
##### OUT = NDF (Write)
Output NDF to contain the product of the two input NDFs.
The title for the output NDF. A null value will cause the title of the NDF supplied for Parameter IN1 to be used instead. [!]

#### Examples:

mult a b c
This multiplies the NDF called a by the NDF called b, to make the NDF called c. NDF c inherits its title from a.
mult out=c in1=a in2=b title="Normalised spectrum"
This multiplies the NDF called a by the NDF called b, to make the NDF called c. NDF c has the title "Normalised spectrum".

#### Notes:

If the two input NDFs have different pixel-index bounds, then they will be trimmed to match before being multiplied. An error will result if they have no pixels in common.
