Solving a matrix equation?
显示 更早的评论
I'm trying to solve the following matrix equation using MATLAB:
AU + UB = C
A, B, and C are known matrices and I want to solve for the matrix U. A and B are square, symmetric, and tridiagonal. Does anyone have advice on how to use MATLAB to efficiently solve this system? Thank you for any help in advance!

40v+5i+0.5i2=0
85v+(i3+i2)4=0
i1=10+i2+i4

1. Consider the following system of equations.
2𝒙𝟏 + 𝟓𝒙𝟐 + 𝟓𝒙𝟑 = 𝟓
4𝒙𝟏 − 𝒙𝟐 + 𝟐𝒙𝟑 = −𝟔
−𝟐𝒙𝟏 + 𝟑𝒙𝟐 − 𝒙𝟑 = 𝟏𝟏
i) Form a matrix for the coefficients of the above system and name it as A.
ii) Find the determinant of A.
iii) Find the inverse of A.
iv) Form a matrix for the right hand values and name it as B
v) Solve the above system.
