hi, there is an issue on "find_basic_var_to_leave_basis" function, because we have to choose the minimum value among the positive p.x(p.basis)./p.updCol s but you choose the minimum value among all of these values, I've tried a lot to solve this problem , unsuccessful tries, I'm really appreciate you to solve this problem sincerely yours,

for example in LP book bazara there is an example which doesn't work in your program if we choose A , b and c like this the problem wouldn't solve at all. A = [ 1 1 1 ;-1 2 -2 ; 2 1 0 ]; b = [4 6 5]'; c = [-1 -2 1]'; inq = [-1 -1 -1]; p = revised(A,b,c,inq,'min'); p.solve;
