python - Using linalg.block_diag for variable number of blocks -


Then I have a code that generates different metrics, these metrics need to be stored in block diagonal matrix. It should be quite simple because I can use the tip: 

  scipy.linalg.block_diag (* AR)

Although I have a problem I'm not sure how many metrics will need to be stored in this way. I want to keep things as (naturally) as possible. I thought of doing something like this: 

  scipy.linalg.block_diag (matrix_list [ii] for category ii (len (matrix_list)))

but It does not work. I can think of some other ways to do this ... but they become quite complicated for everything I think should be very simple.

Does anyone have an idea (or know) out of it?

Thanks in advance!

When you do:

Going to code> a generator expression scipy.linalg.block_diag (matrix_list [ii] ii in range (len ( Matrix_list))) Block_diag , which is not the way to use it.

Instead, use the * operator to expand the argument list in the function call, such as: 

  scipy.linalg. Block_diag (* matrix_list)

html - CSS autoheight, but fit content to height of div -

I have a div in which there are three children- div in the left and middle div: float: left while true: float: true because it is my layout Actually will spoil, I've used ClearFix Hack: .cf {zoom: 1; }. Cf: First,. Cf: {content: ""; Display: Table; }. Cf: After {clear: both; } It still works, but I want to be the right div an indicator. So it should fill 100% of the parent unit of height. How can I complete this? PS is the full code: & Lt; / Div & gt; & Lt; Div class = "mobile_content" & gt; & Lt; H5 & gt; {{Data.titel}} & lt; / H5> & Lt; Table & gt; & Lt; TR & gt; & Lt; Th & gt; Komponist: & lt; / Th & gt; & Lt; TD & gt; {{Data.komponist}} & lt; / TD & gt; & Lt; / TR & gt; & Lt; TR & gt; & Lt; Th & gt; Instrument: & lt; / Th & gt; & Lt; TD & gt; {{Data.instrumente}} & lt; / TD & gt; & Lt; / TR & gt;...

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 ...
