Subject: BNW using Octave instead of Matlab.

This version of BNW should perform the same as the original version. The only difference is that it uses Octave instead of Matlab when running BayesNet Toolbox during parameter learning.

I am calling this BNW_1.02. It can be accessed at:
compbio.uthsc.edu/BNW_1.02

+%
+% CPD = deterministic_CPD(bnet, self, fname)
+% This calls feval(fname, pvals) for each possible vector of parent values.
+% e.g., suppose there are 2 ternary parents, then pvals = 
+%  [1 1], [2 1], [3 1],   [1 2], [2 2], [3 2],   [1 3], [2 3], [3 3]
+% If v = feval(fname, pvals(i)), then
+%  CPD(x | parents=pvals(i)) = 1 if x==v, and = 0 if x<>v
+% e.g., suppose X4 = X2 AND (NOT X3). Then
+%    bnet.CPD{4} = deterministic_CPD(bnet, 4, inline('((x(1)-1) & ~(x(2)-1)) + 1'));  
+% Note that x(1) refers pvals(1) = X2, and x(2) refers to pvals(2)=X3
+% See also boolean_CPD.
+%
+% CPD = deterministic_CPD(bnet, self, fname, pfail)
+% will put probability mass 1-pfail on f(parents), and distribute pfail over the other values.
+% This is useful for simulating noisy deterministic functions.
+% If pfail is omitted, it is set to 0.
