Matrix Operations
... A.5. The column space The column space of a matrix is the span of its columns. This is equal to the span of the pivot columns. The pivot columns are themselves linearly independent, and so form a basis for the column space. For example, if B is as in (A.14), then the pivot columns are the first, sec ...

... matrices can be multiplied using dot products if the number of rows in one matrix equals the number of columns in the other matrix. The matrices to be multiplied in this manner do not need to have the same dimensions or number of components; however, one matrix must have the same number of rows as t ...
