Today's guest blogger is Josh Meyer, a Technical Writer for the MATLAB Math and Big Data teams. He is going to discuss a common issue encountered in scattered data interpolation, and how to fix it!... read more >>

I'm happy to welcome back Damian Sheehy as guest blogger. Last time Damian wrote about how Natural Neighbor interpolation addresses FAQs in scattered data interpolation. In this blog he will answer a FAQ on adaptively editing a Delaunay triangulation.... read more >>

I'm happy to welcome Damian Sheehy as this week's guest blogger. Damian works on the development of geometry-related features at MathWorks. He will provide answers to two frequently asked questions; one on scattered data interpolation that he will cover in this blog and the other on Delaunay triangulation that he will cover in the next. Over to you, Damian...... read more >>

Recently, Lucio and I wrote a post on detecting line segment intersections. We confessed in the post that we had not been exhaustive in our treatment. We also received many interesting... read more >>

Today I am writing this post in collaboration with my friend and colleague, Lucio Cetto. Ever need to know if two line segments intersect? There are lots of ways to do this, and I... read more >>

Recently there was an email making the rounds at MathWorks about how to calculate the area volume under a surface. Not surprisingly, there were several methods chosen, based... read more >>

Ever wanted to know if some points of interest were inside a region? You can answer that if the region is specified as a polygon in MATLAB. The key is... read more >>

Ever been in the situation where you accidently used a variable named something else in MATLAB and it caused you a problem? Ever done it with a variable named clear? It... read more >>
