Hello
Is it possible to write these as 1-1 assignment? 
given.
given. A is 
, b is 
and 
is 
. u and l are 
matrices
, b is and is . u and l are matrices
The problematic part is the sum and the 
or 
condition. How should I modify this?
or condition. How should I modify this?lambda_2k1 = max((b-sum(A*x_c))/A(:,k)) + (u(k) - l(k))/2;

Maybe this? I am assuming that the prelim val is a vector the same size as A(:,k)
prelimVal = (b-sum(A*x_c))/A(:,k);
val1 = prelimVal(A(:,k)<0);
val2 = prelimVal(A(:,k)>0);
lambda_2k1 = max(val1) + (u(k) - l(k))/2;
lambda_2k = min(val2) - (u(k) - l(k))/2;

Yes you do. Also, I think you may want to make sure the sum is summing the elements in the dimension you need them to be. If they are not, use sum( . . . , 2).
