英文解释: In matrix multiplication, if two matrices A and B satisfy AB=BA, we say that these two matrices are commutative. The commutativity of matrices usually implies that there is a certain special structural relationship between them. For example, if both A and B are diagonal matrices, or...
matrixtheory. Keywords:productofmatrices;partitionedmultiplication;elementarytransformation 0引言 在高等代数以及线性代数的教学中,矩阵是一个重要的教学内容,由矩阵的理论可知,矩阵的乘法不同 于数的乘法,矩阵的乘法运算不满足交换律,即:当AB有意义时,BA未必有意义;即使AB与BA均有意义, ...

Matrix multiplication and inverse We know that only matrices whose number number of columns of first matrix and number of rows of second matrix are equal can be multiplied and these numbers form the order of the resultant matrix respectively. By inverse of a matrix B we mean the matrix B...

The matrix multiplication of two different matrices is possible only when the columns of the first matrix are equal to the rows of the second matrix; that is, consider two matrices Ap×q, Br×s, then the multiplication of these two matrices is po...

Matrix Multiplication: The multiplication of two matrices is possible provided they have certain dimensions. The dimensions of a matrix are denoted asm×nwhich denotes that the given matrix containsmrows andncolumns. Now we can define the multiplication of two matricesAandBprovided their dimensions ar...
The associative law for matrix multiplication maybe checked as follows:(aligned) ([(AB)C]_(i j)) =∑_(k=1)^n(A B)_(i k) C_(k j)=∑_(k=1)^n ∑_(l=1)^n A_(i l) B_(l k) C_(k j) =∑_(l=1)^n A_i(B C)_(l j)=[A(B C)]_(i j)(aligned)Use...
