%Engineering 6, Fall 2006, Problem 9.1 Solution %(Product costs calculation) %Suppress extra lines in output and set fixed short display format compact ; format short ; clc; clear; %Clear command window and variables %Define a 5x3 matrix of the product costs (in 1000s of dollars, % with the first column being materials costs for products 1 % through 5, the second column being labor costs, and the third % column being transportation costs). A = [7 3 2; 3 1 4; 9 6 5; 2 5 3; 8 2 1]; %Define a 5x4 matrix of the quarterly production volume (in 1000s % of units, with each column representing one of the quarters).
