Talking through your code is an excellent way to find bugs. By discussing the code you have written line by line, you are forced to understand it better. This is a common practice at most software… read more >>
Sometimes you will do a calculation where the answer looks like ‘0’ or ‘1’ or some other number like that. The natural thing to do is to do a test like this: if (answer ==… read more >>
In this short video, I explore the math behind this joke: An infinite number of mathematicians walk into a bar. The 1st orders a 1 beer. The 2nd orders 1/2 a beer. The 3rd orders … read more >>
I love getting well formed question and challenges from fellow MATLAB users. This week I got one that works very well as a video. The problem was trying to index into a vector with a vector of… read more >>
I think it is best to do these tutorials based on solving realistic coding challenges. In helping to write the code for the next MATLAB contest, I had a situation where I wanted two images to be… read more >>
A question that comes across my inbox from time to time is how to save the state of a GUI between session. There are few methods for doing this, one is using the HGSAVE command to save the .FIG file… read more >>
This blog is just one of many resource available to people that want to learn how to use MATLAB. I want to point you to several tutorials that are available for MATLAB.
You will find lots of… read more >>
In the recent Puzzler about the spiral, most of the code that was produced went along the following: Create the spiral matrix Find the indices of the ‘1’s in the binary targets… read more >>
I recently got an e-mail from a MATLAB user that had a large dataset in Excel. They wanted to import the data and “take the average of the graph”. It turns out that meant fitting a… read more >>
I am about to leave for a recruiting trip to Carnegie Mellon University. Be sure to stop by the booth and say hello (or ARGHHH! if I see you on Friday, International Talk like a Pirate Day!) If you… read more >>
