What's the inverse of a 2x4 matrix?
balandron [24]
Mxn Matrices do not have an inverse solution for m ≠ n, so your 2x4 will not have a solution. 

<span>Generally, inverting matrices is done through finding the determinant of the square matrix and then performing an operation on the matrix based on the size of the matrix. </span>

<span>Wikipedia has a good article on Matrix inversion, take a look there for more information.</span>
