PFilters

Documentation about pfilters is in progress. Some examples:

% get directory listing --> cell array --> just names
pipe dir | num2cell | getfield([],'name')

% same, but store in variable and show
pipe g = dir | num2cell | getfield([],'name'); g

% borda count example
pipe x = [3 2 1 -1 10] | sort^2 | sort^2

% define pfilter and apply to single input
pfilter borda = sort^2 | sort^2
x = [3 2 1 -1 10] | borda
% ans: 4     3     2     1     5

% apply pfilter to vertical cell array
x = {[3 2 1 -1 10]; [10 8 6]; [1:5 0]} | borda
 
 % change all m-files in dir pfilters and store them in pf
 pfilter f = preadf | strrep([],'relative','rela') | pwritf([],'pf')
 g = dirf('pfilters','*.m') | f
