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 !

Glenn
