Given two lines and find matrix representation of transformation (in standard base) which switch lines each others and find all invariant lines of .
I need to find a unique description of Nul A, namely by listing the vectors that measure the null space.
For the matrix A below, find a nonzero vector in the null space of A and a nonzero vector in the column space of A
Find a vector in the null space of A that is not the zero vector
Suppose that A is row equivalent to B. Find bases for the null space of A and the column space of A.
Can I exchange column and then use the row transformation when converting a matrix into a row echelon form?
Find k such that the following matrix M is singular.
[1 2 1 \n -1 0 2\n 2 1 -3] reduced the following matrix row echelon form.
