This six and a half minute video shows a function being created in MATLAB, then it shows a subfunction being added. Functions are a way of adding to the MATLAB language. This video shows the… read more >>

In the last six months, this blog has taken a sharp turn towards being a video tutorial blog. There are other blogs that have been doing this for a while too. I recently got word about a great… read more >>

I was working with a MATLAB user that had a large number of data points in the form of x,y,z triples. He was mostly interested in the density of these data points over the range of the data. At… read more >>

This six minute video shows you how to use the debugger and other tools to step through complicated code and understand what is really going on. By taking a complicated expression and breaking it… read more >>

Two minute video explains scalar and vector expansion.
This helps in situations where you are adding a scalar to a matrix and shows how to expand a vector for a similar effect.
