We don't need to do anything there in a in our first row first column in second rope, we have an entry of negative one and be in our first column and second row. The absolute value of a number may be thought of as its distance from zero along a number line; this interpretation is analogous to the distance function assigned to a real number in the real number system. So I'm assuming you want a matrix B such that a known matrix A when multiplied by B can commute, that is AB=BA. My advice is: don't think about numbers in the matrices if you can avoid it, think in terms of linear transformations. Find all 22 matrices B such that AB=BA This problem has been solved!

A 2 = 29 45 36 56. of columns in A=No. I understand that A and B must both be mxm in size, allowing multiplication in both directions (AB and BA). just pick anything so that Im(B) = Ker(A), but Im(A) != Ker(B). The reason is simple as well: [math]AB [/math] and [math]BA [/math] are matrices of different sizes, so they can never be equal. Find all matrices B such that AB = BA. All Rights Reserved.
