Formatting numbers
We often need to display numbers, in GUI, text files or maybe the console window (Matlab Desktop). Matlab has built-in support for this using the fully-documented num2str, sprintf and format
functions. Unfortunately, these built-in functions, useful as they are for simple needs, have several limitati... | {"url":"http://undocumentedmatlab.com/blog/formatting-numbers","timestamp":"2014-04-19T17:02:24Z","content_type":null,"content_length":"249433","record_id":"<urn:uuid:555efa1b-250a-4ca8-bf61-537fe523aba9>","cc-path":"CC-MAIN-2014-15/segments/1398223203422.8/warc/CC-MAIN-20140423032003-00412-ip-10-147-4-33.ec2.internal.... |

Synthetic division (Finding all zeros)
Show that the given value of c is a zero of P(x), and find all other zeros of P(x) (Enter NONE in any unused answer blanks.)

What Is Perspective Drawing
In text books that teach drawing, often they speak of “one-point perspective”, “two-point-perspective”, “vanishing point”. In this page, i explain what they mean, in terms of the math concept of
linear projection. Once you understand them, you'll see that these terms are very misleading.
