Description
When the values of
n_chans - 1
channels are set to zero,dss.dss0()
returns aValueError: expected square matrix
message. This is because the passed input matrixc2
is one-dimensional (because it has 1 feature only, corresponding to the not-null channel).Proposed fix is to leave it 2-dimensional by removing
squeeze()
.
