Error in : The 'Initial conditions' parameter must be a scalar, vector, or matrix. When you specify a vector, its length must be equal to the number of delay elements in the filter.
When you specify a matrix and the block is doing frame-based processing, the matrix must have the same number of columns as the input signal. For sample-based processing, the matrix must have one column for each element of the input signal. In both cases, the number of rows in the matrix must equal the number of delay elements in the filter.
