 Items(10) /1 (Dual) quasi newton 0 39 (5/20/2011 1:57:00 PM) comp.soft-sys.sas Can any one direct me to read papers about (Dual) quasi newton algorithm that is used when running the CALL NLPQN code, as I need to understand this algorithm ...ayaa help in CALL NLPQN inside PROC IML 0 340 (3/24/2011 7:56:56 PM) comp.soft-sys.sasproc iml; start fun(K); f = sumf; sumf=0; do i = 1 to 3; sumf = sumf + (estvar*lambda[i])+ (g[i]* k)**2 /(lambda[i]+ k)**2; end; return (f); finish fun; start con(k); c=j(4,1,0); sumc1=0; do i =...ayaa Call NLPQN 0 225 (3/17/2011 11:20:38 PM) comp.soft-sys.sasI have three questions, would you please help me in them: 1. How can I use each column of a certain matrix as if it is a column vector instead of being column in a matrix? 2. Here is a nonlinear programmin...ayaa Using vectors in single NLP constraint inside proc iml with call statement 0 40 (3/16/2011 10:18:33 PM) comp.lang.cI have two variables that are stored in a data set and also are stored as matrices and vectors. I want to formulate only one constraint that is a function of all the data set's observations (or elements of thes...ayaa Using vectors in single NLP constraint inside proc iml with call statement 0 29 (3/15/2011 7:15:19 PM) comp.lang.pythonI have two variables that are stored in a data set and also are stored as matrices and vectors.
