Here at The MathWorks we are always concerned with useful ways of displaying data. A heat map is a graphical representation of data where the values taken by a variable in a two-dimensional map are… read more >>

I was recently answering a question that came in from a MATLAB user on this blog. In the end, the question was really one where he was doing a calculation and storing the result in scalar Y. When he… read more >>

I hate to pick one of Jiro’s files for Pick of the Week, because he is quickly catching me in total number of downloads and I really do not need the competition!
However, I can not resist… read more >>

I recently got a question via e-mail from a reader of this blog. This MATLAB user wanted to know:
If you are thinking about another tutorial, can you show if it is possible to build a dynamic GUI,… read more >>

Here is a question from the front lines of technical support at the MathWorks.
This MATLAB user had three images that they wanted to view at once so they could compare them to one another. The… read more >>

Sometimes showing the data in a plot is just not enough. You need to be able to emphasize the parts that are the most important for the viewer of the plot. ShadePlotForEmphasis will do just that.
I… read more >>

As I mention quite frequently, the best way to become Pick of the Week is to write code that solves a problem that I am having or a problem I think many other people are having. That is how I found… read more >>

In MATLAB, with tooltips, you can know what the value of a line is at a given point:

But if you want to know the value of an arbitrary point in a figure, you will want gtrack:

This is a nice… read more >>

I never even knew I needed this function until I saw it. This function basically makes your date ticks scale to the appropriate time scale, be it years, quarters or months. Very nice for that… read more >>

Here at the MathWorks, one of our Core Values is Continuous Improvement. Part of that is about being process oriented- “Clock building is better than time telling.”
Following that Core… read more >>
