Fundamental solution of homogeneous linear equations: Ax=0 with Det(A)=0 with MathNet

Image
1 I am trying to solve a system of homogeneous linear equations like Ax=0. Here is an example matrix which has already been reduced for simplicity: 1 2 | 0 3 6 | 0 The solution I am hoping to get to is at least [ 2, -1 ]. But the fundamental solution is folow: [2C; -1C]. You can see than Det(A)=0 and Rank(A) =1; Of course you know that such systems have trivial solution [0,0]. I am trying: Matrix<double> A = Matrix<double>.Build.DenseOfArray(new double[,] 1, 2 , 3, 6 , ); Vector<double> B = Vector<double>.Build.Dense(new double 0, 0 ); var result = A.Solve(B); //result = Nan, Nan Please help me find solution for such tasks by MathNet, because in real task the dimention of A more than 20. The solving for this problem: Math.Net system of linear equations with a 0 value in solution doesnt work for my situation (B=0, Det(A)=0). Thanks c# linear-algebra mathnet linear-equation share | improve this question edited Nov 15 '18 at 7:0

Bash not responding after sudo pm2 log|app2 command, can only type

-2 please help as I can't seem to exit from 'forever typing mode' in my ubuntu server command line after typing the below command: sudo pm2 log|app2 firstly it shows that command app2 is not found and then subsequently whatever I type, it just doesn't process, even CTRL+C. Whatever I typed will just be shown on command line like the picture below . app2 is one of my process in pm2 but I guess it has to do with the wrongly '|' typed in between. Thank you so much! bash ubuntu sudo pm2 share | improve this question asked Nov 15 '18 at 7:00 cristie09 cristie09 44 6 Posting information in screen shots is NOT recommended on SO, kindly post it in text format in CODE TAGS button. – RavinderSingh13 Nov 15 '18 at 7:19 Have you tried pressing enter and then ctrl + D ? – Socowi Nov 15 '18 at 8:17 @Socowi I tried, it doesn't work :( – cristie09 Nov 15 '18 at 13:52
