Jiro<\/a>‘s Pick this week is bubblebath<\/tt><\/a> by Adam Danz<\/a>.<\/p>

Adam is no stranger to File Exchange and File Exchange Pick of the Week. He is even more active on MATLAB Answers<\/a>. In fact, this entry by Adam stemmed from a question<\/a> on MATLAB Answers. The original poster asked for ways of creating non-overlapping randomly placed circles within a region, with an ability to specify some parameters such as number of circles and min\/max radii.<\/p>

Let’s look at an example. Here, we will create circles with 10 linearly spaced different radii ranging from 1 to 10.<\/p>

S.circSize = [1 10];\r\nS.nSizes = 10;\r\nS.supressWarning = true;\r\nbubblebath(S);\r\n<\/pre>\"\" 
Next, we specify the exact set of radii for the circles.<\/p>
S.circSize = [0.5 1 1.5 3 5 20];\r\nS.nSizes = NaN;\r\nbubblebath(S);\r\n<\/pre>\"\" 
I appreciate the effort he took to create this entry after some discussions on MATLAB Answers. He has also updated his entry based on the comments.<\/p>
The other thing I really like is the detailed documentation (help) he includes with the function and the thorough error-checking for the input arguments. Those of you who have read some of my recent posts (this<\/a> and this<\/a>) know that I am a big fan of the new Function Argument Validation<\/a> that was introduced in R2019b. I understand that Adam wrote his function in an older release, but once he upgrades to the newest release, I encourage him to give it a try!<\/p>
Lastly, I’d like to give a shout-out to a few other entries that were mentioned in the MATLAB Answers post.<\/p>
