Combinations with Repetition, permutations of N elements taken from the vector V, with repetitions. If a disembodied mind/soul can think, what does the brain do? See array size limit or preference panel for To complete our considerations about permutation and combination, we have to introduce a similar selection, but this time with allowed repetitions.It means that every time after you pick an element from the set of n distinct objects, you put it back to that set. When I use this command PERMUTATIONS WITHOUT REPETITION/REPLACEMENT. 3 4 combs = A(combinator(29,28,'c')) Small improvement: In perms_loop the term "[i*ones(m,1) t]" is slower then assigning [i] and [t] separately. For Matlab 7.8, this is about 30% faster than the original subroutine perms_loop. A permutation of a set of objects is an ordering of those objects. combs = A(combinator(29,20,'c')) COMBINATOR will return one of 4 different samplings on the set 1:N, taken K at a time. That is a memory limitation on your computer. possible data combinations without repetition. You are asking MATLAB to build a matrix that is (5^13)-by-13. This example demonstrates the NB-IoT uplink resource element (RE) grid and waveform generation consisting of the NPUSCH and DM-RS signals.

In distinguishing between combinations allowing repetition and those not, I think it's a question of supply of the objects being selected that's important to consider. Vector Indexing, or vector index notation, specifies elements within a vector. The sections below introduce these physical signals and channels that form the grid along with key concepts including subframe repetition, logical and transport channel mappings, and the corresponding grids for the different configurations. It does not update it because the parameter, inside the function function CN = combs_no_rep(N,K), at the line 343 of combinator.m, results in BC=23.999999999999996 (instead of the correct value, 24). 1 3 I appreciate the speedup!
