Problem 570: Development of Market Shares

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
The market shares of rival fashion firms change each year like the shown graph.

For example loses ``Terry Trend'' $ 15$% of its shares to `Jenny Jetset'' and wins $ 40$% of the shares of``Annette Arrogant''.

Test, using MATLAB, what the shares are after one year (10 years) considering the starting shares: Annette Arrogan 30%, Erich Eitel 40%, Jenny Jetset 10%, Fanny Fashion 5% and Terry Trend 15%. Which firm will rule the market on a long-term basis? Can these questions be answered for arbitrary distribution of the shares in the beginning?
