Below is part of my code, I wrote it with FFTW.set_num_threads() to get parallel fft calculation. However, the for loops "for eachindex" are just serial. Is it possible to rewrite the code in a parallel way? I don't know how to implement it with @parallel, SharedArray or the simple @spawn

By default [M M] (without delimeter like , or ;) means concatenation so it throws error. But I think in julia 0.5 [M, M] should do Matrix of Matricies.

Re: [julia-users] How to make a Matrix of Matrix's?

You can simplify the declaration as follows: MM = Matrix(Matrix(1,2)) You can use comprehensions too: MM = [ randn(5,5) for x=1:2, y=1 ] Here, MM has two rows and one column, and each of its elements is a 5x5 matrix. -- mb On Thu, Jun 23, 2016 at 9:28 PM, Sheehan Olver

Re: [julia-users] indexing over `zip(collection1, collection2)`

My recollection is that part of the indexing interface in Julia (just by convention) is that indexing should be of O(1) (or close to that) complexity. Iterable things, in general, have O(n) complexity to access the n-th element, because you have to traverse the data to get there (the classic

Re: [julia-users] indexing over `zip(collection1, collection2)`

Hi Jacob, In my view, in principle, all "iterators" should be indexable, (at least read-only), *unless *the underlying data is not indexable by nature, e.g. with data that comes from a stream... Doing `zip([1, 2], [2, 3])[1]` should probably just work. I also think that for `Zip`s if the

Sorry, to clarify a little: The things you're zipping are not necessarily indexable (i.e. other iterators), so it's not safe to assume you can always index a Zip. On Thu, Jun 23, 2016 at 2:21 PM, Jacob Quinn wrote: > Most "iterator" types are not indexable, AFAIK. The

Most "iterator" types are not indexable, AFAIK. The typical recommendation/idiom is to just call `collect(itr)` if you need to specifically index. -Jacob On Thu, Jun 23, 2016 at 2:18 PM, Davide Lasagna wrote: > Is there any particular reason why `Zip` objects are
