Support for cell array initial conditions will be removed in a future release. You can either
a. Set InitialConditionsPerChannel and InitialConditionsPerSample to false, and specify InitialConditions as a scalar value.
or
b. Set InitialConditionsPerChannel and InitialConditionsPerSample to true, set FrameBasedProcessing to true, reshape your input to a row vector, and set InitialConditions to a matrix of dimensions Length-by-NumChans, where Length is the delay and NumChans is the number of input channels.
