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 found this example in an Introductory R book in the chapter on Matrices and Arrays The array is > m [,1] [,2] [,3] [,4] [,5] [1,] 0 12 13 8 20 [2,] 12 0 15 28 88 [3,] 13 15 0 6 9 [4,] 8 28 6 0 33 [5,] 20 88 9 33 0 The code is #returns the minimum value of d[i,j], i !=j and the row attaining #the minimum, for square

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

Hi Felicia, A few comments: > - /* CELT can only support up to 20 ms */ > subframe_size = st->Fs/50; > - nb_subframes = frame_size > st->Fs/25 ? 3 : 2; > + nb_subframes = frame_size/subframe_size; This will use six 20ms frames to make a 120ms packet, even for SILK-only mode where frames can be up to 60ms. For SILK, two 60ms frames would be a more

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 file

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

Attached is the amended second patch. It now extends the multistream API as well to 80/100/120 ms and incorporates changes based on Mark's comments.

Hi Ulrich, thanks for the suggestion. My concern is that one of the valid inputs is "2.5", which would require conversion to an int, e.g. x10, but doing something like this would start to affect the code readability.

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

To be decodable by opus_demo, you'll have to add the 8-byte "header". Just put in the length of the packet followed by "0" for the encoder range (0 means "not present"). That being said, from previous experience, the most likely cause of the crash is a bug in your software causing a corruption in Opus. So it's safe to assume that if you can't reproduce

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
