Step-by-step explanation: Mark me as a brainliest . And we'll just keep doing that all the way down until you get to the m-th row. By doing row reduction, we can transfer A to its row echelon form. So now I have the big global 10x10 matrix K, and 4 rows in idx (in the problem is 4 elements and each element has 4 Degree of Freedom, which contribute to a 4x4 idx), then I would have to use an iteration to insert k.1 into K in terms of each row in idx for each iteration. To calculate the sum of elements in each column: Two loops will be used to traverse the array where the outer loop select a column, and the inner loop represents the rows present in the matrix a. So my matrix A transpose is going to be a n by m matrix. I have a matrix with a text field as the Row field, and an integer as the Column field. If one of the dimension is provided, the other is inferred from length of the data.We can see that the matrix is filled column-wise. Matrix can be created using the matrix() function.Dimension of the matrix can be defined by passing appropriate value for arguments nrow and ncol.Providing value for both dimension is not necessary. Here it is for the 1st row and 2nd column: (1, 2, 3) • (8, 10, 12) = 1×8 + 2×10 + 3×12 = 64 We can do the same thing for the 2nd row and 1st column: (4, 5, 6) • (7, 9, 11) = 4×7 + 5×9 + 6×11 = 139 And for the 2nd row and 2nd column: (4, 5, 6) • (8, 10, 12) = 4×8 + 5×10 + 6×12 = 154 And w… Each of these are the entries in each of the rows or columns, depending on how you want to look at it.
