Engineering calculations that Excel is unable to perform alone can be
done using Mathematica. In this example, we calculate eigenvalues
and eigenvectors for a 2x2 matrix. Concise symbolic
results are obtained
from the matrix, as shown at the top of the worksheet. In the rest of the
worksheet, we use numeric calculations to determine system behavior, and a Mathematica graphic plots the system's eigenvectors and projected path.
On its own, Excel has a few hundred worksheet functions. Mathematica Link for Excel extends your reach to thousands of
functions, covering diverse areas
of mathematics, engineering and science.
