WebNov 13, 2012 · If your question is about the use of Matlab, the answer is, of course, elementary. For example, you can switch rows this way: A ( [4 2],:) = A ( [2 4],:) you can multiply a row by a constant this way. A (3,:) = 3*A (3,:) and I'll leave you to figure out how to add rows together. If your question is about the mathematics of reducing A to row ...

In the process of row reducing a matrix we often multiply one row by a scalar, and, as Sal proved a few videos back, the determinant of a matrix when you multiply one row by a scalar, is the determinant of the original matrix, times the scalar. So you can clearly row reduce a matrix to the identity matrix but have a determinant ... WebAug 5, 2015 · I want to take a matrix and, by sing elementary row operations, reduced it to row-reduced echelon form. We assume (1) it is solvable and (2) a unique solution. There is no checking for zeros or anything; it just does row operations. Here is the code: small tyres for trolleys
