argument of a function

[Bertrand Roessli]

Hello,

does anybody know if passing many arguments to 
a function affects the speed of execution?

e.g.

[ff,fp]=crys_int_fit(xsav,x,hkl_crys_AA,genpar,intfsqr,domains_cell,flag_k0,propvec_cell_rlu,propvec_cell_AA,...
               lat_cell,ion_cell,spgsym_cell,spgtrans_cell,moment_cell);

And if yes, how to improve that?

Thank You,

Bertrand
