Re: [go-nuts] Is there a more efficient way to slice a multidimensional matrix using proxy?

The cap fields allow us to resize back to the original size (just the same as a cap in a Go slice). This is not necessary for any case where only slicing to a smaller size is needed. The allocation that we do in making a new *Dense would not be needed if the mat.Matrix returned did not modify its

Re: [go-nuts] Is there a more efficient way to slice a multidimensional matrix using proxy?

Hi kortschak, thanks for replying. Please correct me if I'm not following this right. So on Line 290 of the Dense.Slice() method, the receiver is copied into the variable 't' by dereferencing the

Re: [go-nuts] Is there a more efficient way to slice a multidimensional matrix using proxy?

We implement this for first and second order tensors in gonum.org/v1/gonum/mat[1], which you are welcome to borrow from to extend to third order. Our slice operation[2] is in principle non- allocating (though we do allocate a container for generality - a non- allocating version would simply not

Re: [go-nuts] Go channels overused and hyped?

Thank you for writing this informative post. It and explains the issue well and should be shared with others with the same question. Honestly, Go has made me scared of locks. Every time I think of using one, I realize how bad the actual design of the program is and end up refactoring it. The

snmed, My disappointment with that blog post is that it does not address the larger issue, which some people here have clarified, but to be clear on the larger issue and the various points raised about channels: SMALL BENCHMARKS ARE HARD Benchmarking is harder than it seems, because computers

[go-nuts] Is there a more efficient way to slice a multidimensional matrix using proxy?

So I've written a small Tensor library for purposes of various computations inside a hardware product that my startup is working on. I've implemented in the library, the functionality to slice a matrix similar to matlab using a proxy. The implementation, I have works just fine and does exactly
