I am new to mathematica and having trouble understanding the syntax.

The code:

findMax[{b_, w_}, v_] := Min[Select[Join[Table[If[v[[i]] != 0, \[Lambda] /.Solve[(b + w*(0.5 + \[Lambda]*v))[[i]] == 0, \[Lambda]][[1]], -1], {i, 3}],
    Table[If[v[[i]] != 0, \[Lambda] /.Solve[(b + w*(0.5 + \[Lambda]*v))[[i]] == 1, \[Lambda]][[1]], -1], {i, 3}]], # > 0 &]]

My corresponding matlab code is:

for i=1:3
    if(v(i)~=0)
        a=(-b/w);
        lambdas =(a-0.5)/v(i);
        lmat(ind)=(lambdas);
    end
    ind=ind+1;
end

for i =1:3
    if(v(i)~=0)
        lambdas=(((1-gb)/w)-0.5)/v(i);
        lmat(ind)=(lambdas);
    end
end
%lam=(max(lmat));
%added
lam=(min(lmat));

Is my matlab implementation correct?

Any help would be really appreciated.
