Matlab has a nice feature that lets you chain commands by treating functions as variables. This means that you can write:

a = "foo"; b = feval(a,arg1,arg2,...) |

Now if we want to chain commands acting on the same input we can write:

myfoos = cell{'foo1','foo2','foo3',...}; x = ... chainedFoosOnX = applyChain(x,operators); function x = applyChain(x,operators) for ii = 1:length(operators) x = feval(operators{ii},x); end end |

Of course this example only works for one argument functions but it is simple to see how it would extend to more interesting scenarios.
