Why do I have to duplicate the labels used in classification process?

Dear All, I'm using the BCI Competition dataset IV 2a. I'm working on Left & right hand movement. I extracted data of channels (Fz,Cz,Pz). I filtered data [8-30], then normalized it. I calculated the common spatial patterns of the training dataset using the CSP.m of the Biosig toolbox I want to ...

Error in calculating covariance matrix for common spatial pattern

Hello, I'm using the BCI Competition IV 2a dataset. I want to use the common spatial pattern of the BioSig toolbox. I'm working on 3 channels. I adjusted my dataset into 2 classes (One-vs-Rest scheme) & reshaped my data from 3 dimension matrix into 2 dimension matrix: · Class1 (left motor imager...
