EXPE

Takes the natural exponential of an NDF data structure

This routine takes the natural exponential of each pixel of a NDF to produce a new NDF data structure.

This command is a synonym for expon base=natural.

expe in out

Input NDF data structure.

Output NDF data structure being the exponential of the input NDF.

The title for the output NDF. A null value will cause the title of the NDF supplied for Parameter IN to be used instead. [!]

loge a b

This takes the natural exponential of the pixels in the NDF called a, to make the NDF called b. NDF b inherits its title from a.

loge title="Cas A" out=b in=a

This takes natural exponentials of the pixels in the NDF called a, to make the NDF called b. NDF b has the title "Cas A".

This routine correctly processes the AXIS, DATA, QUALITY, LABEL, TITLE, UNITS, HISTORY, WCS, and VARIANCE components of an NDF data structure and propagates all extensions.
Processing of bad pixels and automatic quality masking are supported.
All non-complex numeric data types can be handled.
