Parameters

trainData
Matrix<(Of <(Single>)>)
The training data. A 32-bit floating-point, single-channel matrix, one vector per row
responses
Matrix<(Of <(Int32>)>)
A floating-point matrix of the corresponding output vectors, one vector per row.
varIdx
Matrix<(Of <(Byte>)>)
Can be null if not needed. When specified, identifies variables (features) of interest. It is a Matrix>int< of nx1
sampleIdx
Matrix<(Of <(Byte>)>)
Can be null if not needed. When specified, identifies samples of interest. It is a Matrix>int< of nx1
update
Boolean
If true, the training data is used to update the classifier; Otherwise, the data in the classifier are cleared before training is performed

Return Value

The number of done iterations
