一、a=[0 -1 4 0 0 -1;-1 4 -1 0 -1 0;4 -1 0 -1 0 0;-1 0 0 4 -1 0;0 -1 0 -1 4 -1;0 0 -1 0 -1 4] c=[0 5 0 6 -2 6] b=c'
if ax=b find the solution useing the followinng methods:(1)Gaussian elimination,(2)LU factorization,(3)Matlab operator.
二、a=[2.0 -3.0 2.0;1.9 -3.0 2.2;2.1 -2.9 2.0;6.1 2.1 -3.0;-3.0 5.0 2.1] x=[x1 x2 x3]
c=[1.01 1.01 0.98 4.94 4.10] b=c'
if ax=b find the solution useing matlab pinv and operator.
三、for a=[122 41 40 26 25;40 170 25 14 24;27 26 172 7 3;32 22 9 106 6;31 28 -2 -1 165],determine (1)the eigenvalue nearest 100 and (2)the smallest eigenvalue.
