As said in #1921 (closed) the NCLS filter we had was doing nothing more than the UCLS filter. That is why I removed it from the application choice and also from OTB.
Rationale
This filter was doing the same thing as an unconstrained least square. Have a look at the for loop here and replace all the matrix to see that correction=0
