Adding callbacks to lines and axes in MATLAB 8

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…. 更多内容 >>

Interuptable callbacks and BusyAction in MATLAB 5

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… 更多内容 >>

Using synthetic data to test algorithms in MATLAB 2

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… 更多内容 >>

Using Datetick with Plotyy in MATLAB 6

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… 更多内容 >>

Debugging: creating a line with empty data

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… 更多内容 >>

Exploring data through a series of vizualizations 1

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,… 更多内容 >>

Searching for permutations of a string in a list in MATLAB 4

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… 更多内容 >>

Non-uniform spacing for surf in MATLAB

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. … 更多内容 >>

uicontextmenu and ButtonDownFcn in MATLAB 7

When you use ButtonDownFcn in MATLAB, your callback is given an automatic input called hObject. This hObject is the handle of the object that you interacted with to invoke the callback, which makes… 更多内容 >>

Understand If statement behavior on vectors 2

In teaching new MATLAB users, I often see them accidentally use a vector as an input to an if statement. This is not likely what they intend and it is often an overlooked syntax error. In this… 更多内容 >>
