sMap=sompak_init(sData,ft,init_type,cout,ct,xdim,ydim,topol,neigh)
SOMPAK_INIT Call SOM_PAK initialization programs from Matlab.
sMap=sompak_init(sData,ft,init_type,cout,ct,xdim,ydim,topol,neigh)
ARGUMENTS ([]'s are optional and can be given as empty: [] or '')
sData (struct) data struct
(matrix) data matrix
(string) filename
[ft] (string) 'pak' or 'box'. Argument must be defined, if input
file is used.
init_type (string) string 'rand' or 'linear'
[cout] (string) filename for output SOM, if argument is not defined
(i.e. argument is '[]') temporary file '__abcdef' is
used in operations and *it_is_removed* after
operations!!!
[ct] (string) 'pak' or 'box'. Argument must be defined, if output
file is used.
xdim (scalar) Number of units of the map in x-direction.
ydim (scalar) Number of units of the map in y-direction.
topol (string) string 'hexa' or 'rect'
neigh (string) string 'bubble' or 'gaussian'.
RETURNS
sMap (struct) map struct
Calls SOM_PAK initialization programs (randinit and lininit) from
Matlab. Notice that to use this function, the SOM_PAK programs must
be in your search path, or the variable 'SOM_PAKDIR' which is a
string containing the program path, must be defined in the
workspace. SOM_PAK programs can be found from:
