ParseAtributesMADX_2_AT()#: determines atribute and sets field in sxs{i} structure AT

created 6-sept-2012

atfrommadx()#: function atfrommadx(seqfilemadX,E0,outfilename)

tansform madX sequence file (savesequence) file into AT lattice structure.

This procedure reads a saved lattice (sequence in madx) in madX

and converts it to an AT lattice

(madx comands to save the sequences :

_______ MADX code _________

use,period=sequencename1;

use,period=sequencename2;

use,period=sequencename2;

SAVE,FILE=’seqfilemadX.seq’;

___________________________

seqfilemadX.seq will contain sequencename1 sequencename2 sequencename3

in the correct format in a single file

)

The routine outputs a Matlab macro with all the AT defitions and variables as

in the madX file

The order of the declarations is the same in the two files.

declarations that contain other variables are moved to the end. (this may not be enough)

Works also with single madX files not containing comands, only

definitions.

parameters:

- seqfilemadX=name of the mad8 lattice file

- E0 = design energy

- outfilename (default: seqfilemadX_AT_LATTICE.mat)

buildATLattice()#: given a list (cell array) of elements with specified field Spos (center of element (madx default)) in a

vector returns a cell array with elements without Spos field and

appropriate Drifts spaces between. Drifts of the same length have the same name.

reshapeToCellArray()#: if CEL_CEL is a cell array of structures and cell arrays it converts it a

cell array of structures.
