In this code I am getting the error :

C#

CS0246	The type or namespace name 'Matrix<float>' could not be found (are you missing a using directive or an assembly reference?)

C#

#region Generate the training data and classes

Matrix<float> trainData = new Matrix<float>(trainSampleCount, 2);
Matrix<float> trainClasses = new Matrix<float>(trainSampleCount, 1);

Image<Bgr, Byte> img = new Image<Bgr, byte>(500, 500);

Matrix<float> sample = new Matrix<float>(1, 2);

Matrix<float> trainData1 = trainData.GetRows(0, trainSampleCount / 3, 1);
trainData1.GetCols(0, 1).SetRandNormal(new MCvScalar(100), new MCvScalar(sigma));
trainData1.GetCols(1, 2).SetRandNormal(new MCvScalar(300), new MCvScalar(sigma));

Matrix<float> trainData2 = trainData.GetRows(trainSampleCount / 3, 2 * trainSampleCount / 3, 1);
trainData2.SetRandNormal(new MCvScalar(400), new MCvScalar(sigma));

Matrix<float> trainData3 = trainData.GetRows(2 * trainSampleCount / 3, trainSampleCount, 1);
trainData3.GetCols(0, 1).SetRandNormal(new MCvScalar(300), new MCvScalar(sigma));
trainData3.GetCols(1, 2).SetRandNormal(new MCvScalar(100), new MCvScalar(sigma));

Matrix<float> trainClasses1 = trainClasses.GetRows(0, trainSampleCount / 3, 1);
trainClasses1.SetValue(1);
Matrix<float> trainClasses2 = trainClasses.GetRows(trainSampleCount / 3, 2 * trainSampleCount / 3, 1);
trainClasses2.SetValue(2);
Matrix<float> trainClasses3 = trainClasses.GetRows(2 * trainSampleCount / 3, trainSampleCount, 1);
trainClasses3.SetValue(3);

How can I resolve it ?

What I have tried:

I am trying SVM (Support vector machine) for object classification which uses these libraries. Can anyone provide the alternate source code for SVM

VS is usually very helpfull. Read the message "are you missing a using directive or an assembly reference?)" and more VS helps you on things like this by right click the message. Than it gives you sometimes the Option to solve it.

"provide the alternate source code for SVM": Do you think this really helps?

It seems you missing reference to an assembly or using directive. Please check for the namspaces

yes I clicked the link and it also suggested me to add some reference. But which namespace or using directive shall I add OR for VS2010 which reference and for VS2015 which NuGet Package to install ?

This is exactly the same issue as CS0246 the type or namespace name 'emgu' could not be found (are you missing a using directive or an assembly reference? )[^], which I already told you how to fix.

That's what I am trying to ask Richard MacCutchan which namespace or using directive shall I add OR for VS2010 which reference and for VS2015 which NuGet Package to install ?

Or could anyone give me a link for any online documentation for that?

Why not read the documentation? And please make the effort to search Google for the links yourself.
