Bring Matrix to Reduced Row Echelon FormAsk Question Asked 7 years, 1 month ago Modified 7 years, 1 month ago Viewed 408 times 0 I have been trying to bring a matrice to RREF but I have run into trouble, and I can't really see where I mess up: Let a = -3/2. Bring the mat...
Reduced Row Echelon Form of a matrixJohn Fox
Compute Reduced Row Echelon Form of Symbolic Matrix Compute the reduced row echelon form of the following symbolic matrix. syms a b c A = [a b c; b c a; a + b, b + c, c + a]; rref(A) ans = [ 1, 0, -(- c^2 + a*b)/(- b^2 + a*c)] [ 0, 1, -(- a^2 ...
Reduce the matrix ⎡⎣⎢14−2−1−12−6−1512⎤⎦⎥[1−1−64−1−15−2212] to reduced row-echelon form How is my answer incorrect? I performed the row operations: 1) R2=4R1−R2R2=4R1−R2 2) R3=2R1+R3R3=2R1+R3 3) R2=R2/−3R2=R2/−3; 4...

首先RREF(A)表示的是对A进行了有限步骤的基本行操作(elementary row operations)以后获得的、形式满足RREF(Reduced Row Echelon Form)的方阵;根据行等价(row equivalence) 的定义可知RREF(A)与A存在行等价关系。根据定理--“如果A行等价于(row equivalent to)B,A的大小为m*n,那么存在一个大小为m*m的可逆矩阵R...
