Hi, I am trying to minimize a function with 9 variables using - QuadraticOptimization[{q,c},{a,b}] Here q is a 9X9 matrix whereas c is a 9X1 matrix.

{q, c} part is working fine when I use {a, b} = {{}, {}}, which means there are no constraints over the values of 9 variables. I get the o/p in this case.

However, I want to put a constraint that these nine variables have only positive values. How to put this constrain in form of {a, b}. According to the definition of a and b, ({a, b} is equivalent to ax+b>= 0), I should have a =1 and b = 0 for each of the nine variables. So I tried {{1, 0}, {1, 0}, {1, 0}, {1, 0}, {1, 0}, {1, 0}, {1, 0}, {1, 0}, {1, 0}}. However it did not work.

Will appreciate any suggestions. Thanks
