Join Patrick Royal for an in-depth discussion in this video Understanding data types, part of Learning MATLAB.
Let's look at the ways in which MATLAB represents and understands numerical data. …Normally, when programming, it's easy to ignore data types and just assume that …the program knows what it's doing. The assumption is that MATLAB will give …the exact answer to any calculation because it uses so many decimal points …that the error is extremely tiny. However these tiny errors can cause huge …problems, making it important to have some grasp over the difference between …different types of ints and doubles. For an example of this see …roundoff_error.m in the exercise files. This graphs two exponential decay …sequences on a logarithmic graph. We'll go into more detail about the exact …mechanics behind graphing and how to use graphing functions in a later video.…
Both sequences change by the exact same amount each time. …The only difference is the starting point, so they should be parallel. …We would expect both sequences to go uniformly downward in a straight line, …but that's only true of sequence x. Running this sequence yields the graph …
