Does the 1<0 (approximate rendering) indicate real value 1 complex phase 0, complex(1,0)?
Does j indicate sqrt(-1)?

Easy using matrix notation:
A = [1.46j,0.9j,-0.36j;0.36,-0.42,-1.345;0.9j,1.65j,0.42];
b = [1;0;1];
I = A\b
I =
-0.0059 - 0.4749i %I1
0.0079 - 0.3480i %I2
-0.0040 - 0.0184i %I3

Hi Najiya,
Alex's answer has a typo in that the last entry in A is 0.42 rather than j0.42. So:
A = [j*[1.46,0.9,-0.36];[0.36,-0.42,-1.345];j*[0.9,1.65,0.42]];
b = [1;0;1];
I = A\b
I =
0.0000 - 0.4841i
0.0000 - 0.3357i
0.0000 - 0.0247i
I have no idea why I1 disagrees with what is in the book, although books have been known to be wrong. Unlike everything on this website.
