Linear Problem - Find Optimal Solution

A businessman is considering opening a small specialized trucking firm. To make the firm profitable, it is estimated that it must have a daily trucking capacity of at least 84,000 cu. ft. Two types of trucks are appropriate for the specialized operation. Their characteristics are as follows: Truck Cost Capacity(Cu. ft) Drivers needed small $18,000 2,400 1 large $45,000 6,000 3 Note that the truck 2 requires 3 drivers for long haul trips. There are 41 potential drivers available and there are facilities for at most 40 trucks. The businessman's objective is to minimize the total cost outlay for trucks... click for more

linear algebra: finding eigenvalues

Hello. I'm trying to do a principle component analysis of the following file of "good values" - to create a good data signature. I need to find the eigenvectors of each data series. How do I derive the eigenvalues (or eigenvectors) and what are they from this data set? (If you could explain how to do it in matlab, that would be great - but it's not necessary for me to understand how it works) Thank you. "Does every line in the excel file represent a 16x16 matrix?" I'm not sure. I would have to say yes, if it is the only way to get the eigenvalues. I was just given the data as a known good set of data and asked to do a principal component analysys (academic). To do a PCA, I... click for more
