해가 유일하지 않은 경우 linsolve 는 경고를 발생시키고 하나의 해를 선택하여 반환합니다. 연립방정식에 해가 없는 경우 linsolve 는 경고를 발생시키고 모든 요소를 Inf 로 설정하여 X 를 반환합니다. 기호 객체가 아닌 숫자형 행렬에 대해 linsolve 를 호출하면 MATLAB ® linsolve 함수가 호출됩니다. 이 함수는 실수 인수만 받습니다. 연립방정식에서 복소수를 사용하는 경우 sym 을 …

Solve System of Linear Equations Using solve. Use solve instead of linsolve if you have the equations in the form of expressions and not a matrix of coefficients. Consider the same system of linear equations. 2 x + y + z = 2 − x + y − z = 3 x + 2 y + 3 z = − 10. Declare the system of equations. syms x y z eqn1 = 2*x + y + z == 2; eqn2 ...

linsolve (MATLAB Functions) MATLAB Function Reference linsolve Solve a linear system of equations Syntax X = linsolve(A,B) X = linsolve(A,B,opts) Description X = linsolve(A,B)solves the linear system A*X = Busing LU factorization with partial pivoting when A is square and QR factorization with column pivoting otherwise.

Both of them are direct solver to solve linear systems (opposing to iterative solver). mldivide does perform the tests for A in solving Ax=b.

Calling linsolve for numeric matrices that are not symbolic objects invokes the MATLAB ® linsolve function. This function accepts real arguments only. If your system of equations uses complex numbers, use sym to convert at least one matrix to a symbolic matrix, and then call linsolve. See Also
