Re: [swift-evolution] Basic element-wise operator set for Arrays, Arrays of Arrays, etc.

If I read Nicolas's post correctly, I think he's more arguing for the ability to create syntax that allows Swift to behave in a similar way to Numpy/Matlab. While Swift already does allow you to define your own operators, the main complaint is that he can't define the specific operators he would

Re: [swift-evolution] Basic element-wise operator set for Arrays, Arrays of Arrays, etc.

If you're simply looking for elementwise multiply without performance requirements, map(*) is a very succinct spelling. Performant implementations for these operations like you have in Matlab rely on special math libraries. Apple platforms have Accelerate that makes this possible, and other

[swift-evolution] Basic element-wise operator set for Arrays, Arrays of Arrays, etc.

Dear all, In swift (just as in many other languages) I have been terribly missing the operators like .* ./ .^ as I know them from MATLAB/Scilab. These operators are very handy and do element-wise operations on vectors or matrices of the same size. So for instance A*B is a matrix
