Dear All, Could someone give me some pointers (just a guide as to what functions I need to look at would be fine) as to how I go about this simple problem please;
The problem looks like this; Choose x1 to x4 such that you minimize the MAXIMUM ABSOLUTE value returned in the vector result of this matrix problem; [x1,x2,x3,x4].[ -0.38 -0.52 0.68 -0.29 ] [ -0.39 -0.42 -0.12 0.49 ] [ -0.40 -0.20 -0.45 0.26 ] [ -0.39 0.03 -0.39 -0.36 ] I hope the formatting comes out ok , I did this on a Mac !
