4.3 Linear Combinations and Spanning Sets
... In the previous section, we looked at conditions under which a subset W of a vector space V was itself a vector space. In the next three section, we look at the following problem. If W is not a vector space, how can we build a vector space from it? Once we answer that, we will try to …nd the most e¢ ...

Matrix Inverses Suppose A is an m×n matrix. We have learned that
... We have also seen that matrix multiplication is defined only if a particular compatibility condition € amongst the matrices being multiplied and is met their product: if AB makes sense, and A is m × n and B is p × q, then necessarily n must equal p and the product AB is m × q. For this and a number ...
