Arithmetic to Functional Converter
1 view (last 30 days)
I was wondering if anyone knows of a way to convert arithmetic to functional synatx. For example, I'd like to convert the string
Now, this was a very simple example. It gets a bit harder with more "complicated" expressions.
I assume MATLAB already does this, under the hood somewhere. There should be a way (either documented or not) to access this. Any insights?

Are you just trying to evaluate algebraic statements provided in string format?
If so, try "eval":
>> a = 4
>> b = 6
>> str = 'a+b'

Its easy, IF you look at this the right way.
First, pre-parse the expression to determine that 'a+b.*c' has three variables in it, a, b, and c. Define objects a, b and c. Now overload the plus and times operators to actually use bsxfun.
Finally, let MATLAB do the operation, using an eval. You CAN make this work, but you will need to be careful and think it out.

Hi, Did you manage to find a method in MATLAB that already implements this. I am trying to do the same thing I am sure that somewhere in matlab there should already be a method. If you could let me know that would be greatly appreciated.
