A MATLAB function that implements (8.7) is
software/pdf_exp_ord.m. The module
software/module_exp_ord.m implements
the feature set corresponding to
software/pdf_exp_ord.m. Feature resynthesis is implented by
software/module_exp_ord_synth.m and testing is implemented by
software/module_exp_ord_test.m. These functions have an input argument
pdf_type, which can
select integral solution (8.4) if pdf_type=2, or
SPA (8.7) if pdf_type=0, or SPA with error term if pdf_type=1.
The module also has the option of including the indexes of the largest bins
in the features (if add_idx=1).
The module is tested using software/module_exp_ord_test.m.
