WebThe cross product inputs 2 R3 vectors and outputs another R3 vector. The matrix-vector product inputs a matrix and a vector and outputs a vector. If you think of a matrix as a set of row vectors, then the matrix-vector product takes each row and dots it with the vector (thus the width of the matrix needs to equal the height of the vector).

Sal could have multiplied a 2x2 zero matrix with the 2x3 matrix to obtain a resulting zero matrix. Having a 2x3 zero matrix makes no difference as having a 3x3 matrix.

WebThe short answer is no, while it is true that row operations preserve the determinant of a matrix the determinant does not split over sums. We want to compute det (M-lambda I_n) which does not equal det (M)-det (lambda n). The best way to see what problem comes up is to try it out both ways with a 2x2 matrix like ( (1,2), (3,4)). Comment ( 4 votes) WebOccurrences [ edit] The mortal matrix problem is the problem of determining, given a finite set of n × n matrices with integer entries, whether they can be multiplied in some order, possibly with repetition, to yield the zero matrix. This is known to be undecidable for a set of six or more 3 × 3 matrices, or a set of two 15 × 15 matrices. [6]
