Detailed Description

Deinterleave i.e. Reorder input realvec.

This is designed, so that its output can potentially be meaningfully split by the Parallel MarSystem.

if you want to deinterleave samples (possibly with different channels containing different numbers of samples): transpose, then deinterleave using this marsystem, then transpose again (using the Transposer MarSystem).

Same basic functionality as DeInterleave. As opposed to that one, this is not matrix multiplication based, and therefore has additional support for rows (observations) of different lengths.

• e.g. the second input row has only 5 entries instead of the 8 of the first (rest is assumed to be zero padded)
  • then the result for three sets (numSets - control = 3) would not only reorder the elements of the 8 elements (ordered 0th,1st,2nd,3rd,4th,5th,6th,7th) of the first row to the new order 0th,3rd,6th,1st,4th,7th,2nd,5th but also reorder the sedond row in the following order: 0th,3rd,1st,4th,2nd(,5th,6th,7th following - i.e. unchanged).

In general this means that: The input realvec is assumed to be organized in numSets equal modulo sets - i.e. in a n*numSets,n*numSets+1,...,n*numSets+(numSets-1) manner. This marsystem ensures that the output will be ordered with the sets grouped together - i.e. in a numSet[0][0],numSet[0][1],numSet[0][2],...,numSet[0][inObervations/numsets], numSet[1][0],numSet[1][1],numSet[1][2],...,numSet[1][inObervations/numsets], ..., numSet[numSets-1][0],numSet[numSets-1][1],numSet[numSets-1][2],...,numSet[numSets-1][inObervations/numsets] manner. Note that, if the number of observations is not divisible by the number of Sets, then the first "rest" groups will have one element more than the remaining groups. (With "rest" being the rest of the division of the number of observations by the number of Sets).

Controls:

• mrs_real/numSets [w] : deinterleave this number of observations.
• mrs_realvec/sizes [w] : realvec vector(i.e. one dimensional realvec) - each element i corresponding to the i-th row for controlling this input-row's number of elements to be interleaved;
