Re: Matrix help needed
sorry I neglected to notice your edit. The fact the matrix is nonsquare makes a great deal of difference, and the answer to your question now mostly depends on how this is being applied.
When m>n there will be a single solution (null being possible), when n>m there will be infinite solutions. For most real applications in the former case (m>n) a row reduction will find B. There is no easy way to row reduce without using a computational device.
