I don't think the pipe symbol '|' is being used for anything in MATLAB syntax. Would it be a good idea to use it to make a family of BSXFUN operators? For example, instead of
you could do things like
No products are associated with this question.
Instead of introducing new operators and limit the backward compatibility, you can implement a new class easily, which uses BSXFUN implicitly for the standard operators. See FEX: int64 class as an example. Here the standard arithmetic is implemented for INT64, which was missing in older Matlab versions. The same can be done for DOUBLE or better for a new derived data type to avoid confusions.
I occasionally use the kron() function, and I probably should use bsxfun() more. What I seem to be banging my head up against: I saw the light with MATLAB when I grasped the beauty and compactness of regular 2-d oriented array/vectorization. The fact that it tended to make my MATLAB scripts faster did not hurt either.
Recently, I am feeling constrained: for the kind of stuff that I am doing, MATLAB vectorization can only take me so far. I believe that what I am longing for is tensor math. Is this a direction that TMW will/should head for, or is it too exotic/hard to make fast libraries/something else?
I'd like to write:
a = ones(2,4,3); g = cat(3,1,2,3);
%1. short-hand for: %for t = 1:3, % R1(:,:,t)=a(:,:,t)*g(t); %end R1 = a.*g; R1(:,:,1) =
1 1 1 1 1 1 1 1
2 2 2 2 2 2 2 2
3 3 3 3 3 3 3 3
%2. short-hand for: %R2 = zeros(2,4); %for t = 1:3, % R2=R2+a(:,:,t)*g(t); %end R2 = a*g; R2 =
6 6 6 6 6 6 6 6
