A C++ Library For IIR Filter

Answer : There's octave, an open-source MatLab clone, you could use its implementation (but it will likely require you use use its special matrix type). Searching for "C++ IIR filter" finds a bunch of other projects, such as: Signal Processing using C++ dspfilterscpp There are also a variety of books on the subject, for example: C++ algorithms for digital signal processing In general, implementation of an IIR filter is very easy. Numerical robustness and efficient use of your computer hardware are more difficult, but they require knowledge of your specific application (e.g. resampling, etc) so aren't really suited for library implementations. You could also try GNURadio (gnuradio.org), which contains all sorts of components for software defined radio (including iir filters). It was originally all C++, now it is a bunch of modules written in C++ with python bindings, but you should still be able to use the C++ code directly.

Android: Permission Denial: Starting Intent With Revoked Permission Android.permission.CAMERA

Answer : Remove this permission <uses-permission android:name="android.permission.CAMERA"/> I faced this error executing my app in android 7. After tests I noticed user permission wasn't in project A but it was in project B, that I only tested in android 5 devices. So I remove that permission in project B in order to run it on other device that targets android 7 and it finally could open. In adittion I added the fileprovider code that Android suggests here https://developer.android.com/training/camera/photobasics.html Hope this helps. hi you can use these permission in your manifest file with other permission, <uses-feature android:name="android.hardware.camera.any" android:required="true" /> <uses-feature android:name="android.hardware.camera.autofocus" android:required="false" /> If still it not working then may be you are using android M,SO you need to programmatically add permissio

C# WPF - ScrollViewer + TextBlock Troubles

Answer : This works: <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <ScrollViewer HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" Name="Scroller"> <TextBlock HorizontalAlignment="Stretch" VerticalAlignment="Stretch" MinWidth="100" Width="{Binding ElementName=Scroller, Path=ViewportWidth}" TextWrapping="Wrap" Text="Some really long text that should probably wordwrap when you resize the window." /> </ScrollViewer> </Window> Without more detail, the best I can do is provide the standard way of doing this. Basically, host your element (which has a minimum size) in a scroll viewer; when th

Can't Seem To Run Tesseract From Command Line Despite Adding PATH

Answer : The PATH variable should include directories only, not files, such as C:\Program Files (x86)\Tesseract-OCR . So It seems there are two version for Windows, 4.00 and 3.05 -- 4.00 is still buggy. I installed the 3.05 version and seems to work fine now. Here is where I got the 3.05 version. https://github.com/UB-Mannheim/tesseract/wiki The solution is the following you have to add cd first ... Example: cd C:\Program Files (x86)\Tesseract-OCR C:\Program Files (x86)\Tesseract-OCR> tesseract --version

Connect To Openvpn Using Username And Password

Answer : Yes it's possible. To do this, you have already an OpenVPN server installed, and the user created in the server. The easiest openvpn client is network-manager. If you are using Ubuntu run: aptitude install network-manager-openvpn restart network-manager Now click on the network-manager applet, select configure VPN, and setup a new open-vpn connection. Set the gateway to you server Set the type to Password Point your CA to a copy of your server’s ca.crt and everything should just work Attached is a simple client configuration file that will work. Edit it to match your server’s settings where appropriate. You will need this and your ca.crt in the same directory. On linux my file is called /etc/openvpn/client.conf ############################################## # Sample client-side OpenVPN 2.0 config file. # for connecting to multi-client server. ############################################## # Specify that we are a client and that we # will be pulling certain config file d

Creating A Pdf File In Android Programmatically And Writing In It

Answer : So apparently the code I was using wasn't compatible with android, hence the error I was getting. Below you'll find the correct code that actually works right (for creating a pdf file, putting some content in it, saving in and the opening the newly created file): PS: For this you'll need to add the jar of iTextG to your project: // Method for creating a pdf file from text, saving it then opening it for display public void createandDisplayPdf(String text) { Document doc = new Document(); try { String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/Dir"; File dir = new File(path); if(!dir.exists()) dir.mkdirs(); File file = new File(dir, "newFile.pdf"); FileOutputStream fOut = new FileOutputStream(file); PdfWriter.getInstance(doc, fOut); //open the document doc.open(); Paragraph p
