matrix - Calculating distances between points in matlab -


I need some advice on how to create a script to calculate the tangent velocity of data, in fact tangent velocity (VT ) = R * W W is the rotational speed which is 100 r / s in this case. R radius, therefore, imagine a disc, as you go along the edge, R increases, so the price of the weight increases. My problem is, behind the spinning disk, I entered the data, the data is in the matrix of 100x100 data points, however, my disk's radius is 25, i.e., the first 25 data points between the matrix of my disk left and right And moves up and down. Is it possible to write a script that can calculate the distance between the center of the disk and the data point, it would give me a value for R then W and this is the data point multiplied by the specific R value?

Regards, Jar

qt - How to prevent QAudioInput from automatically boosting the master volume to 100%? -

I have been trying to use Qt5 multimedia to record audio with QAudioInput, however, when I see If QAudioInput is started, it increases the master volume of my sound device to 100%. How can I prevent QAudioInput from changing the master volume? My current development platform is Linux with PalsAdio (with flat audio disabled). How can I use QAudioInput : QAudioDeviceInfo device_info = QAudioDeviceInfo :: defaultInputDevice (); QAudio format format; Format.setSampleRate (44100); Format.setChannelCount (1); Format.setSampleSize (16); Format.setCodec ("Audio / PCM"); Format.setSampleType (QAudioFormat :: SignedInt); Format.setByteOrder (QAudioFormat :: LittleEndian); Std :: cout & lt; & Lt; Device_info.deviceName (). ToUtf8 (). ConstData () & lt; & Lt; Std :: endl; QAudioInput * default_device = new QAudioInput (device_info, format); QIODevice * default_io_device = default_device-> Start (); a QAudioInput.setVolume () method is not you I ...
