Permute input symbols using a set of shift registers with specified delays
Library
Convolutional sublibrary of Interleaving
Description 
The General Multiplexed Interleaver block permutes the symbols in the input signal. Internally, it uses a set of shift registers, each with its own delay value.
The input can be either a scalar or a frame-based column vector. It can be real or complex. The input and output signals share the same sample time.
The Interleaver delay parameter is a column vector whose entries indicate how many symbols can fit into each shift register. The length of the vector is the number of shift registers. (In sample-based mode, it can also be a row vector.)
The Initial conditions parameter indicates the values that fill each shift register at the beginning of the simulation. If Initial conditions is a scalar, then its value fills all shift registers; if Initial conditions is a column vector, then each entry fills the corresponding shift register. (In sample-based mode, Initial conditions can also be a row vector.) If a given shift register has zero delay, then the value of the corresponding entry in the Initial conditions vector is unimportant.
