analysis. In many applications though there will be a need for doing analysis based upon
certain conditions specific to your test. For example, if I performed a two hour long test
on an aircraft component, I may want to develop a script that looks through the data
and runs FFTs if/when certain conditions are met. Doing this fairly simply analysis that
has a couple if-statements may be more difficult in a standalone GUI.
Most times a combination of standalone GUIs and custom analysis scripts will offer the
best of both worlds to complete your analysis. There are a lot of options out there but it
can be difficult to go through and compare them. Below we’ve condensed the list to a
few more well-known software packages.
MATLAB
MATLAB is a programming language specifically developed for linear algebraic
operations. Because of this initial core design and focus, it is a hugely popular tool for
data analysis. Engineers would have used MATLAB is college and entered the workforce
already with a knowledge and preference for this (MathWorks is smart with their pricing
to offer significant discounts to universities and students).
