# MATLAB Puzzler: Finding the two closest points29

Posted by Doug Hull,

Here is a new MATLAB Puzzler.
Given two vectors representing the X and Y coordinates of some points, find the two closest points in Cartesian space.

n = 10;
x = rand(1,n);
y = rand(1,n);

Brett and I took very different paths to solving this problem, he knows more about the statistics toolbox than I… read more >>

# MATLAB Puzzler: Removing columns and rows from binary matrices36

Posted by Doug Hull,

I am trying something new this week: the MATLAB Puzzler.
Rather than just work one of the Practical Examples directly, I am doing it in two parts. The first I will pose the MATLAB puzzler and say how much code it took me to solve it. This is not a contest,… read more >>

# Practical Example: Placing a sampling grid in a polygon part two1

Posted by Doug Hull,

This is the second video in this series, it shows you how to run a very simplistic optimization. For a simple problem like this one, the algorithm is more than sufficient to find a correct answer to what size edge is needed set the grid spacing such that the right… read more >>

# Practical Example: Placing a sampling grid in a polygon4

Posted by Doug Hull,

A while back, I posted a video about how to place points randomly inside of an arbitrary polygon. [Click here] This video prompted a question about how to place points in a more systematic manner. If you are only allowed to change the edge length of an equilateral triangular grid,… read more >>

# Practical example: Intersecting a circle with a line series4

Posted by Doug Hull,

As with all the videos in this practical example series, the process of developing code is more important than the particular problem that is being solved. In this video, we will be covering topics that are covered in earlier videos:

Nested subfunctions
Run configurations
FIND
Custom plots with Handle Graphics

However now we… read more >>
