Matrix help? PLEASE HELP OMG

OpenStudy (anonymous):

Sorry, my computer took a few minutes to load. Present the data in four matrices. Choose an element from each matrix and tell what it represents.

OpenStudy (anonymous):

You just split it vertically into 4 different matricies: So the matrix representing B would be [0.6, 0.6, 0.35, 0.22, 0.1) T would be [0.95, 1, 6, 0.19, 0.82] etc.... element n for any of these matricies represents the component level (mg/kg) of a specific sample n. So if I take element 2 of B's matrix, that tells me the component level of B's 2nd sample.

OpenStudy (anonymous):

You only need one matrix to present the data. Any more would be inefficient. Create a 5x4 matrix whose rows represent what sample you're using, and whose columns are the specific component (B,T,E, or X). Denote this matrix as A. Fill in the entries exactly how your data is presented. Then a[ij] represents the ith sample at a given jth component level.

would the matrix be [.06 .95 .9 18.5] [.06 1.05 .73 13.5] [.35 6 5.6 49 ] [.22 .19 2 19.5] [.11 .82 2.5 26 ] ?

That's horizontally. You want 4 matrices, and that way produces 5. Up to down, not left to right.

[.06 .06 .35 .22 .11] [.95 1.05 6 .19 .82] [.9 .73 5.6 2 2.5] [18.5 13.5 49 19.5 26] ?
