I submit the following matrix to both MATLAB and R
x= 0.133 0.254 -0.214 0.116
0.254 0.623 -0.674 0.139
-0.214 -0.674 0.910 0.011
0.116 0.139 0.011 0.180
MATLAB's inv(x) provides the following
137.21 -50.68 -4.70 -46.42
-120.71 27.28 -8.94 62.19
-58.15 6.93 -7.89 36.94
8.35 11.17 10.42 -14.82
R's solve(x) provides:
261.94 116.22 150.92 -267.78
116.22 344.30 286.68 -358.30
150.92 286.68 252.96 -334.09
-267.78 =358.30 -334.09 475.22
inv(x)*x = I(4)
and solve(x)%*%x = I(4)
Is there a way to obtain the MATLAB result in R?
Thanks for any help.
