Does anyone have an intuitive way of understanding matrix multiplication? Specifically, why we take a column of B and a row of A for AxB? There are a few helpful indications of how this can be interpreted (in terms of linear transformations), but I was wondering if anyone had found a stronger (i.e. more natural/intuitive) way of justifying it to themselves. |

Does anyone have an intuitive way of understanding matrix multiplication? Specifically, why we take a column of B and a row of A for AxB? There are a few helpful indications of how this can be interpreted (in terms of linear transformations), but I was wondering if anyone had found a stronger (i.e. more natural/intuitive) way of justifying it to themselves. --Wanmike 13:44, 8 November 2006 (EST)
