- extract the current Sammon mapping in the form of
a DATASET
SYNOPSIS
int sammon_extract_map
(mode)
ARGUMENTS
int
mode
One of SAMMON-MAP-flags, indicating whether the
map should be copied to the datasets input or output vectors.
RETURNS
NULL in case an error occured, a pointer to a valid DATASET
structure otherwise.
FUNCTION
This function is used to extract a trained map in the form of a DATASET.
It is constructed by copying everything (except the input vectors) from
original_set (see SAMMON-VARIABLES). After that, all input
vectors are copied from map. The SetText field is set to
"x-dimensional Sammon mapping" and the CreationDate field is set.
If mode = SAMMON_OUTPUT, all input vectors are copied from original_set
and the map values are used to fill the output vectors.
NOTE
The number of inputs of the new set will be equal to map_dim; the number
of output will be original_set->NumOutputs.
