Row operations on matrix
WebSo as long as you keep track of the effects of the row operations you use, you can reduce your matrix to triangular form and then just calculate the product of the numbers down the diagonal. An example. Suppose you want to evaluate the determinant. You notice that row one has a factor 2, so you want to apply the row operaton R 1 ← (1/2)R 1. WebFinal answer. The given row operations, when performed on a matrix A, result in the given matrix B. Find the determinant of A. R3 −8R1 +R2 6R2 +R3 ⇔ R1 ⇒ R2 ⇒ R3 ⇒ B = ⎣⎡ 1 0 0 −2 −3 0 5 8 4 ⎦⎤ Decide if A is invertible. A is invertible. A is not invertible.

BB = repmat ( {row},Nmc,1); CV=repmat ( {Coh},Nmc,1); I have to write a code which considers the first cell of both BB and CV together and do the calculations as in the first code and then consider the second cell of BB and CV together and do the same calculations. The result would be a 5*2 cell matrix as Nmc=2.
