Hello, I am dealing with numeric vectors 10^5 to 10^6 elements long. The values are sorted (with duplicates) in the vector (v). I am obtaining the length of vectors such as (v < c) or (v > c1 & v < c2), where c, c1, c2 are some scalar variables. What is the most efficient way to do this? I am using sum(v < c) since TRUE's are 1's and FALSE's are 0's. This

I would like to have your comments regarding: 1) drivers/rhino.c ------------------ The following patch addresses some problems in drivers/rhino.c. Or that is what I think. I don't use this hardware. The patch: 1. Eliminates some usefulness definitions. 2. It removes code that evaluate the time. I can't see how the code actually does useful work. 3. The evaluation time code allocates memory. I don't see how that memory is freed. Index: b/drivers/rhino.c =====================================...

...a need for it to be split out into a separate function? If it had a simple and concise interface then it may make sense even with one call, but in this case the arguments that it requires are numerous and peculiar to the specific implementation in the calling function. > + bytes_per_frame = IMIN(1276,(out_data_bytes-3)/nb_frames); The current code uses this formula because with up to 3 frames per packet, in the worst case the combined packet will require nb_frames*bytes_per_frame + 3 bytes (where bytes_per_frame is the code 0 packet length, as it is here). However the worst case is worse...

In debugging I saw: opus_multistream_encoder.c line 760 if(!vbr) max_data_bytes = IMIN(max_data_bytes, 3*st->bitrate_bps/(3*8*Fs/frame_size)); max_data_bytes after this code becomes -2 where as before it was 10200. I suspect it was because st->bitrate_bps was set to -1000 to indicate Auto bitrate. I imagine Max bitrate (-1) has a slightly similar effect. then in the same c...

Hi, I just checked in a fix for the bug you reported. Let me know if it works.

Hello, I have created a spatial map of temperature over an area thanks to interpolation. So I have temperature data everywhere on my map. My question is: how can I find temperature data on my map for a specific location according to coordinates? For this, I have a data frame containing 4 columns: "x" for longitude, "y" for latitude, "z" for altitude" and

Hi all: ;I wish to raise something that has, in my opinion, not been properly dealt with. With the iminent release of icecast2 and vorbis 1.0, I feel that it needs to be sorted out. The problem is that of how to launch an ogg stream from a web browser. In short, what metafile should be used, or do we need to invent our own? Let me illustrate the problem. Using MP3 streaming as an example, we have...
