I had to implement that once (in Delphi), but I would not have recognized it by reading matlab-code* Thumbs Up | :thumbsup:

Hi !
if the input data is a list of points how can i select randomly just 2 points from it ?
how to convert this line :
%% Randomly select 2 points
idx = randperm(number,num); sample = data(:,idx);

int number = data.Count; // Total number of points
int bestInNum = 0; //Best fitting line with largest number of inliers
int bestParameter1=0 ,bestParameter2=0; //parameters for best fitting line
for (int i = 1; i < iter; i++)
{
//Randomly select 2 points
Random rnd = new Random();
//....??
}

int idx = rnd.Next(0, myList.Length);

That is assuming a Generic List, and only returns a single, random index. Described here[^] Smile | :)

thanks

but if i try like this ,is it possible?

IList<point>[] data;
IList<point> model;
int number = data.Length;
//Randomly select 2 points
Random rnd = new Random();

int idx = rnd.Next(2, number);model=data[idx];

int idx = rnd.Next(2, number);

That would give you a random number between 2 and number, not two numbers. If you want another random number after the first, you'd have to ask for the "Next" number again (between min, max).

You should give it a try yourself and come back when you have trouble at a specific point. The code looks pretty much straight forward to translate with the help from google.

problem in code Port.ReadTo

Hi,
I have problem in this code

string w;
        private void Port_DataReceived(object sender, SerialDataReceivedEventArgs e)
        {
            string[] data_from_computer;
            data_from_computer = new string[3];
            int x ;
            //int n_bytes = Port.BytesToRead;

            w = Port.ReadTo("ST").ToString();
            if (w != string.Empty)
            {
                data_from_computer[0] = ""+w[0];
                data_from_computer[1] = ""+w[1];

               label2.Text = data_from_computer[1];

            }

where must be send data twice for least to response the code
I mean for example I need send this data "STA"
the code

w = Port.ReadTo("ST").ToString();

is read ST and store A in W
But if send data first time for example "STA" the program or code not work
then must be data "STA""STA" then the code is work why??

note Port is name for serialport

You could go to theier site: http://www.iocomp.com/Downloads/Default.aspx[^] and download it from there.

Of course you will probably have to pay for it, but you knew that, didn't you?

You might want to go into a bit more detail as to what you're looking for. Seven segment WHAT and for which platforms? Windows Forms? WPF? Web apps?

I took your requirements as described (I even filled in some missing bits) and coded this for you:

public class SevenSegment
{
    private bool[] Segments;

    public SevenSegment()
        : this(new bool[7])
    { }

    public SevenSegment(bool[] segments)
    {
        if (segments == null)
            throw new ArgumentNullException("segments");

        if (segments.Length != 7)
            throw new ArgumentException("segments");

        Segments = segments;
    }

    public bool this[int i]
    {
        get { return Segments[i];  }
        set { Segments[i] = value; }
    }
}

Do you know that this site not only has forums for asking questions but also tons of articles that present solutions for all kinds of things?

I entered "codeproject 7-segment" into Google and found several articles for that. The first one I clicked also explained how to add it to the toolbox of Visual Studio. If you had done this yourself, you would have saved yourself time and us.

Hi All,

I want a call log of a PBX box like inbound, outbound calls.
Call Summary like Duration of a call, Timing of a Call etc. in C#. how do i get it?

OriginalGriff29-Apr-15 21:31

You should talk to the people who created your PBX - they should provide technical support and will know more about their product than we will. If they don't, then find another supplier and demand your money back!

We can't tell you: we have no idea what PBX you are using, or how it allows you to get access to the information. You need to talk initially to the people who do know - the manufacturers.
