The input to the svmtrain function is a matrix with the dimension 151x22.

While applying the svmtrain function with the above matrix ( as shown below ), I am getting a structure. Inside the structure, there is a field named "support vectors".

The size of this support vectors is 42x22.

How does this subset gets formed ?
