Find and return Binomial Coefficients (BCs) in a matrix up to N.
The function BINOMIND(N,K,SPEED) does not use loops (apart from a redundant check) or division nor indeed factorials to generate the Binomial Coefficients (BCs). It simply constructs the lower-triangular Pascal matrix and does a simple lookup to get the desired BC.
BINOMIND is much faster than NCHOOSEK at creating matrices of BCs if you set SPEED to TRUE and also has a basic integrity check to compare it with nchoosek. It can return 3 lots of data: comb,binTable, errorRate but you can just use it to find combinations by default.

1.1.0.0 | I added more input parameter checking, an extra input parameter, SPEED as well as a warning message for COMB values above a predefined tolerance limit. I also improved the documentation of the function. |
