Multiplication of 2*2 and 2*1 matrix
WebLet a, b, c ∈ R be all non-zero and satisfy a 3 + b 3 + c 3 = 2. If the matrix A = `((a, b, c),(b, c, a),(c, a, b))` satisfies A T A = I, then a value of abc can be ... WebThe answer will be a 2 × 2 matrix. We multiply and add the elements as follows. We work across the 1st row of the first matrix, multiplying down the 1st column of the second matrix, element by element. We add the resulting products. Our answer goes in position a11 (top left) of the answer matrix.

WebA matrix with one column is the same as a vector, so the definition of the matrix product generalizes the definition of the matrix-vector product from this definition in Section 2.3. … Web6 iun. 2016 · For example: A=[3,-2;2,-2] times v=[1;-1] works, but fails if A=[1,2;3,4]. The problem seems to be that in Matlab matrix multiplication the elements in row A are multiplied by the corresponding columns in B. Here B has only one column, and needs that the column elements in A be multiplied by the corresponding row elements in B.
WebIf both arguments are 2-D they are multiplied like conventional matrices. If either argument is N-D, N > 2, it is treated as a stack of matrices residing in the last two indexes and broadcast accordingly. If the first argument is 1-D, it is promoted to a matrix by prepending a 1 to its dimensions. After matrix multiplication the prepended 1 is ...
