To do this, we transform fully fuzzy linear system in to two crisp linear systems, then obtain the solution of this two systems by using the pseudo inverse matrix method. Numerical examples are given to illustrate our method.doi:10.5899/2013/jsca-00012S. Moloudzadeh...
(a) Find the inverse of the matrix \begin{bmatrix} -4 &-12& 21\1& 2&-4\1& 3& -5 \end{bmatrix} (b) Use the answer from part (a) to solve the linear system : -4x1 -12x2 + 21x3 =0 x1 + 2x2 - 4x3 = 4 x1...
A square matrix is singular only when its determinant is exactly zero. Tips It is seldom necessary to form the explicit inverse of a matrix. A frequent misuse of inv arises when solving the system of linear equations Ax = b. One way to solve the equation is with x = inv(A)*b. A ...
Using matrix multiplication, we may define a system of equations with the same number of equations as variables as AX=BAX=B To solve a system of linear equations using an inverse matrix, let AA be the coefficient matrix, let XX be the variable matrix, and let BB...
2. Inverse Matrix Method or Matrix Inversion Method or Adjoint MethodThis method is used to solve the system of linear equations.Let’s have a matrix equation:AX=ABPre-multiply with A–1 to both the sides⇒A–1AX=A–1B⇒IX=A–1B⇒X=A–1B...
