MULT

Multiplies two NDF data structures

Description:

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

Usage:

mult in1 in2 out

Parameters:

IN1 = NDF (Read)
First NDF to be multiplied.
IN2 = NDF (Read)
Second NDF to be multiplied.
OUT = NDF (Write)
Output NDF to contain the product of the two input NDFs.
TITLE = LITERAL (Read)
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.
