macro in matlab for incomplete syntax

I wonder if there is a way to create a short cut for incomplete program.( Creating functions can only serve for complete programs, right? )

Like in Stata:

local aa ########

these mean asign the latter apart (########) to former sign (aa) , whatever ######## is, even an incomplete syntax. It could be really really useful.

For a stupid example:

local a valuable1=

local b ^2/4

local c 2

local d =1/4

`a'`c'`b'

it means valuable1=2^2/4=1

if `a'`d' {

valuable2`c'`d'9`b'`b'

}

it means if valuable1=1/4 execute that asign valuable22=1/49^2/4^2/4. In this example, you can see that i create valuable22 by valuable2`c', and asign = to the formula creating 1/49 at the same time by `d'9

Both of 2 example above use ` ' to cite what we need. And those in ` ' can be a incomplete syntax.

Because of being incomplete, we can use the same sets of macro to create many thing easier (not in here, after all just examples)

And it can asign entirely a complete function.It really only depend on what you write at the end of the command local. When syntax become very long, it is very convinient ,such as:

local q ###############################################################################################

local w &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&

local e @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

`q' `w' `e' `w' `e' `q' `e' `q' `w'

even

local r `q' `w'

local y `r' `r`q`w`r`r`r`r'''''''

Using macro for asign a new macro, Imagine that !!!

So, how can i perform the same "function" in matlab?

This exact thing could be achieved, but I'm not going tell you with which function, because it is a terrible idea in Matlab.

I think most useful things can be achieved with anonymous functions.

i take it as a NO. Got it.@Rik

There is no built-in functionality that I know of that would achieve something like this, except for trickery involving eval.

What is it you want to do? I suspect the flexibility you describe can be achieved with anonymous functions. If you have a specific question, feel free to post the link here.

Sorry for responding so late.

I had some practical usage in the past in STATA, but recently i start to learn matlab and want to do same thing in it, that is why i ask.

What do i want to do exactly? Almost everything.

I can tell that you are a matlab expert. You are so familiar with certain function when you need it. so you dont have inner desire to persue such "flexibility", while noob like me does.

I am sure you dont have time to look my STATA do file. But I post one of the many "what i want to do" question for matlab, which is relevent to this and can be achieve by this. Hope you can have a look.@Rik
