Thank you. I will look into that. Am Freitag, 8. Mai 2015 16:03:54 UTC+2 schrieb Isaiah: You will most likely need to install mingw64 compilers, and compile ReadStat yourself. See the Julia README.Windows for install instructions, and https://github.com/WizardMac/ReadStat/issues/13 for

Re: [julia-users] forming an FFT matrix in julia

2015-05-10 Thread Andreas Noack
1. In Julia fft(A) is the 2d DFT of A. You can get MATLAB's behavior with fft(A, 1) 2. I might not understand what you are trying to do, but it appears to me that you can just apply the DFT to the full vector and then sample the elements of the vector. 2015-05-10 22:32 GMT-04:00 Edward Chen

I (and several others who I've spoken with in person) hope you're all able to appropriately balance time spent towards the consulting work vs time spent towards developing the core language, since those will inevitably not overlap as often as everyone would like. The progress that the language

I actually don't think it is really that hard... for the most part, Julia needs better performance and better compatibility in some areas, that haven't received as much attention as of yet... (strings, decimal floats, database access). None of these things will take anything away from what

There is a very long list of interesting possibilities in this thread, but Julia does have a current target audience which it supports with a set of features that increase their utility. It is going to be tricky for those guiding Julia to ensure that things like more generality don't reduce

[julia-users] forming an FFT matrix in julia

2015-05-10 Thread Edward Chen
To whom it may concern: 2 issues: 1. In MATLAB, we can form an nxn FFT matrix by doing fft(eye(n)). In Julia, doing fft(eye(n)) doesn't seem to be giving me the same result. 2. I am actually interested in randomly sampling the rows of a FFT matrix, and doing matrix-vector multiples

I was able to sell Julia recently for a small 2,5 month consultancy project at a research institute. The main difficulty in convincing the client was the uncertain long term support for the language, so I'm very happy to see this Julia Computing LLC up and running. I agree with Scott that a

No, there hasn't been any change on this. It's unclear if anything from the Rust model can actually be leveraged in a dynamic language. On May 9, 2015, at 3:46 PM, Michael Louwrens michael.w.louwr...@outlook.com wrote: Have you had any further thought on this? It seems like it could be

The one thing where I think you should change a bit, is that I think you should be looking at the big picture already when making language design decisions... (for example, the operator for string concatenation ;-), using up back tic for commands, or ~ for DataFrames...). It doesn't mean you

PL/1 (actually Cornell's PL/C, which had a simple REPL) was my very first programming language, back in 1973. At the time, for commercial programming, it was much nicer (IMO) than either Fortran or COBOL... It supported binary floating point like Fortran and decimal floating point like
