问题 How do you write a FREQ rule in iCalendar data format for store's opening hours ? Let's say the store is open every working day (Mon-Fri): from 8:00AM to 5:00PM (or with lunch break from) 8:00AM to 11:00AM and 12:00PM to 5:00PM This would solve the days: FREQ=WEEKLY;WKST=MO;BYDAY=MO,TU,WE,TH,FR , how about the hours though ? Edit: Could I do sth like this? DTSTART;TZID=America/New_York:19970902T080000 RRULE:FREQ=WEEKLY;WKST=MO;BYDAY=MO,TU,WE,TH,FR DURATION=PT9H Would this mean every day from

问题 I have a .wav file, I load it and I get the next spectrogram showing the spectrum in dB http://i.stack.imgur.com/22TjY.png Now I would like to know these values exactly because I want to compare with other wav file, for recognizing if these 4 values are there. http://i.stack.imgur.com/Jun25.png The source to generate that pictures (taken from other stackoverflow example) ## some stuff here for i in range(0, int(RATE / CHUNK_SIZE * RECORD_SECONDS)): # little endian, signed shortdata_chunk data

问题 I'm trying to downsample a .wav audio from 22050 to 8000 using AudioInputStream but the conversion returns me 0 data bytes. Here is the code: AudioInputStream ais; AudioInputStream eightKhzInputStream = null; ais = AudioSystem.getAudioInputStream(file); if (ais.getFormat().getSampleRate() == 22050f) { AudioFileFormat sourceFileFormat = AudioSystem.getAudioFileFormat(file); AudioFileFormat.Type targetFileType = sourceFileFormat.getType(); AudioFormat sourceFormat = ais.getFormat(); AudioFormat

问题 I'm trying to count the frequency of numbers from 1 to 100 on different fields of a table. Let's say I have the table "Results" with the following data: LottoId Winner Second Third --------- --------- --------- --------- 1 1 2 3 2 1 2 3 I'd like to be able to get the frequency per numbers. For that I'm using the following code: --Creating numbers temp table CREATE TABLE #Numbers( Number int) --Inserting the numbers into the temp table declare @counter int set @counter = 0 while @counter < 100

问题 I have the the sample stored in the following list sample = [AAAA,CGCG,TTTT,AT-T,CATC] .. To illustrate the problem, I have denoted them as "Sets" below Set1 AAAA Set2 CGCG Set3 TTTT Set4 AT-T Set5 CATC Eliminate all Sets where each every element in the set is identical to itself. Output: Set2 CGCG Set4 AT-T Set5 CATC Perform pairwise comparison between the sets. (Set2 v Set4, Set 2v Set5, Set4 v Set5) Each pairwise comparison can have only two types of combinations, if not then those

问题 I have a dataframe that looks like the following Utterance Frequency Directions to Starbucks 1045 Show me directions to Starbucks 754 Give me directions to Starbucks 612 Navigate me to Starbucks 498 Display navigation to Starbucks 376 Direct me to Starbucks 201 Navigate to Starbucks 180 Here, there is some data that show utterances made by people, and how frequently these were said. I.e., "Directions to Starbucks" was uttered 1045 times, "Show me directions to Starbucks" was uttered 754 times

问题 Hi there I am looking to combine two data ranges/arrays into one in order to feed them into excel FREQUENCY function. Example: First data range - B5:F50 Second data range - J5:N50 Bins data range - I5:I16 Function definition - FREQUENCY(data_array; bins_array) Basically I am lazy and I don't want to reshuffle my excel script to spit out both datasets side by side so that I can reference them using something like B5:K50 range. Is there any way I can combine both datasets into data_array using

问题 How can I calculate Frequency & Amplitude in As3 with FP9. I got the all raw byte using SoundMixer.computeSpectrum(_testbytes, false, 0); var g:Graphics = this.graphics; g.clear(); g.lineStyle(0, 0x6600CC); g.moveTo(0, PLOT_HEIGHT); var m:Number = 0; for (var i:int = 0; i < 256; i++) { m = (_testbytes.readFloat() * 100); g.lineTo(i*2 , 100 - m); } g.lineTo(CHANNEL_LENGTH * 2, PLOT_HEIGHT); Now Can I get the frequency & amplitude data from it? 回答1: If you have a closer look at the

问题 The FREQUENCY function in Microsoft Excel is useful for generating histograms. The first parameter is an array of data values (E.g. A1:A100). The second one is an array of bin sizes. I want to generate this array from three parameters: Minimum data value: MIN(A1:A100) Maximum data value: MAX(A1:A100) Bin size: constant That is, a formula/function should return the list of wanted values instead of manually putting them in cells. E.g. Consider a minimum value of 10, a maximum value of 100 and a

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 2 years ago . Just wondering if anyone has come by any example code using the ToneGenerator class? I would like to generate tones in the frequency range of about 200Hz to 900Hz.
