Simple chaining of operations (a.k.a. pipe operator) in octave

There is no need for an elaborate pkg or fancy operator to do this.
It's a very simple function and looks perfectly clean to use. Here it is:

pkg load miscellaneous   % provides reduce function
evalf = @(v, f) f{1}(v);
chain = @(v, varargin) reduce( evalf, varargin, v );

That's it!

Example:

add = @(x) @(y) x + y;

L = [4,1,8,8,11,-68,19,11,14,8,0,-67];

chain( L
       , add(100)
       , @char
       , @tolower
       , @strsplit   )

# outputs:
#   ans =
#   {
#     [1,1] = hello
#     [1,2] = world!
#   }
