# 結果: Topic: Practical example

Recently a MATLAB user asked me how to make it possible to work with an array of structures in such a way that she could filter the array of structures and then combine the remaining fields. Once… 続きを読む >>

# Using logical indexing to plot points meeting a specific criteria only.

If you have a vector of coordinate for a set of points, you might want to differentiate those points. To do that a concept called logical indexing will help you pull out a subset of those points… 続きを読む >>

# Sudoku solver in MATLAB by webcam1

From our Japan office via Steve’s blog: This just tickles my fancy, and I think everyone should watch it. … 続きを読む >>

When I teach the MATLAB graphics class for new technical support engineers at MathWorks, I have one major exercise for them to do. This is that exercise. if (typeof(playerLoaded) === ‘undefined’)… 続きを読む >>

# Code review: finding the closest point on a surface

This video shows the implementation of the plan for how to find the closest point on a surface to a given point. This is a numerical approximation that avoids the inevitable complexities of solving… 続きを読む >>

# Set up: Finding closest point on a surface4

This video sets up the plan for how to find the closest point on a surface to a given point. This is a numerical approximation that avoids the inevitable complexities of solving the problem exactly… 続きを読む >>

# Advanced: Speeding up an enumerated string search in a data mining application3

This week, I am going to cover a technique that I used to speed up a data mining application that had a search through enumerated strings looking for all the matches. Using this technique of… 続きを読む >>

# Integrating to find the volume underneath a set of nonuniformly spaced data13

This video covers the use of GRIDDATA, anonymous functions, and QUAD2D to integrate the volume under a set of randomly spaced data points. First an interpolation scheme must be put in place, then a… 続きを読む >>

# Basics: Code review- the thought process in rewriting code for clarity14

This short video covers the thought process of rewriting some code for clarity. The six lines of code are lengthened into twice that. The code is much more readable and maintainable. The problem… 続きを読む >>
