Hello!
Since, as Julien mentioned, it is complex to post matrices, and other mathematical notations on the Blog, then I do recommend the following:
Once you find a nice article online, Copy and Paste the Link BUT tell us in your own words more details about your example and why do you think it is an interesting post!
Example:
My article is found at: http://www.mff.cuni.cz/veda/konference/wds/contents/pdf06/WDS06_106_m8_Ulrychova.pdf
In this article: Example 1 shows us a real life situation of a Shopping scene! 3 people who would like to buy some rolls, buns, cakes and bread from 2 shops. The question is: "which shop is the best to pay as little as possible?"
Tables are given on quantity and prices.
By rewriting each table as a matrix (first table P and second table Q), we can find, for example, the amount spent by Person 1 in Shop 1, by multiplying row 1 of P with column 1 of Q!
Nice, simple and easy!
You can get more details by reading attentively example 1 in the attachment I provided.
What did I learn???
I chose a problem that is used in a Business Math course, and shows how matrices can really be effective and quick in case we have several variables. A matrix gives order to things and facilitate computations!
What do you think?

Hello Zeina,
ReplyDeleteThanks for your post and for the nice articles you have found online! well, the example 1 that you explained shows how matrices can make computations easy and simple, in a Business like situations! when we have many people buying several items from different shops! Interesting!
In your article, I also enjoyed reading example 2. I heard before that matrices were used during wars to encode and decode secret phrases! Example 2 shows an easy to understand example, about encoding the words "white cat" and decoding the words "black dog".
I find this blog interesting in "making sense" what we learn in the class! What is the use of matrices, inverses, multiplication of matrices. etc.
Thanks Zeina,
Darin
