What will be the dimensions of the new matrix formed by multiplying a 2 by 4 matrix and a 4 by 5 matrix?
2 x 5 matrix
What will be the dimensions of the new matrix formed by multiplying a 7 X 2 matrix and a 2 X 6 matrix?
7 x 6A+
Is it possible to multiply a 3 X 2 matrix and a 2 X 3 matrix?
The first matrix has 3 rows and 2 columns, the second matrix has 2 rows and 3 columns. Two matrices can only be multiplied together if the number of columns in the first matrix is equal to the number of rows in the second matrix. In the example shown there are 3 rows in the first matrix and 3 columns in the second matrix. And also 2 columns in the first and 2 rows in the second. Multiplication of the two matrices is therefore possible.
Can a 3 x 2 matrix be added or subtracted with a 4 x 3 matrix?
No.Two matrices A and B can be added or subtracted if and only if they have the same number of rows and columns. That is a 3 x 2 matrix can be added or subtracted only with another 3 x 2 matrix.
How do you multiply a 3 x 2 matrix and a 2 x 3 matrix?
This is not going to be easy without the sigma notation, but here's the best that I can do. Let 3 x 2 matrix A = {aij} where i = 1, 2, 3 and j = 1, 2 and 2 x 3 matrix B = {bkl} where k = 1, 2 and l = 1, 2, 3 Then their product is the matrix C = {cmn} where m 1, 2, 3 and n = 1, 2, 3 such that cmn = am1*b1n + am2*b2n That is, the element in row m and column n of C is the sum of the products of the elements in the mth row of A and the nth column of B
