A callback is a function that gets called when you perform certain actions. For instance, you might want something to happen when you click on a line in MATLAB, or when you move the mouse in MATLAB…. read more >>
If you push a button in a MATLAB UI and this starts a long calculation, what do you want to have happen if the user pushes the button a second time? Interuptable property and BusyAction property of… read more >>
This week we are making up some data and doing a couple of visualizations. We then modify the data to do a reality check on a simple algorithm. This allows us to gain confidence in our algorithm… read more >>
I have been using MATLAB tables lately. In doing that, MATLAB will store meta data with your numeric data. I was bringing data in from Excel files. Each column name will eventually become a… read more >>
I often say that one my greatest qualifications for troubleshooting MATLAB code is that I know I am not that clever, so I have to simplify things until I can understand them easily. It works really… read more >>
Recently, I needed to plot two different sets of time series data on the same axes, but they were at different scales. In this simplified example, I show how you can change the x-labels to display… read more >>
In this video we are sorting through some data making a different line for all the data points that match certain criteria. At some point in the algorithm none of the data meets the criteria. This… read more >>
When we get unknown data, we do not always know where it will lead us. This video shows the series of visualizations that I went through to answer a question about my data. By showing the process,… read more >>
In this video a colleague was looking in a large list to see if each element was a permutation of any element of a shorter list. I name these lists Haystack and Needle so it is easy to remember… read more >>
In this video, we will use non-uniform spacing for the X vector going into a surf plot in MATLAB. This allows us to selectively increase the resolution of a graphic in the more important regions. … read more >>
