However, there are plenty of linear operators that can't be undone (because they have squashed something flat), and the matrices representing these operators (with respect to any given basis) must therefore be not-dividable-by. A warning message is displayed if A is badly.

If A is an n-by-n matrix and B is a column vector with n components, or a matrix with several such columns, then X A\B is the solution to the equation AX B. A. If A is a square matrix, A\B is roughly the same as inv(A)B, except it is computed in a different way. To divide Matrices, element-by-element, the following formula is useful. For instance, rotating the plane clockwise by a certain angle "undoes" the anticlockwise rotation of the plane by the same angle. We thought it will be also necessary you have a grip on the element-by-element Matrix division in Matlab. So "dividing by" a matrix would correspond to "undoing" the effect of a linear operator.

Or using the operator (left matrix divide).
MATRIX DIVISION MATLAB B'/A SOFTWARE
I would recommend trying a 2 by 1 column vector with variables for entries, and two 2 by 2 matrices, also with variables for entries. Matlab is a software package that makes it easier for you to enter matrices and. If you didn't know that already, then you should try to convince yourself that it's true, in a simple class of special cases. That is, matrix multiplication corresponds to composition of linear operators. For motivation ,consider the ordinary real numbers $\mathbb=I$.ĭo you know why matrix multiplication is defined in such a weird way ? It is defined thus, so that the effect on a column vector of left-multiplying it by one matrix, and then left-multiplying the result by another matrix, is exactly the same as the effect of left-multiplying by a single matrix that is the product of those two matrices. There is a way to performa sort of division, but I am not sure if it is the way you are looking for. Check that the two matrices can be multiplied together.
