Graphics challenge 10

Posted by Doug Hull,

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’) {var playerLoaded = false;}(function isVideojsDefined() {if (typeof(videojs) !== ‘undefined’) {videojs(“mathworks-brightcove-player”).on(‘loadedmetadata’, function() {playerLoaded = true;});} else {setTimeout(isVideojsDefined, 10);}})(); This is… read more >>

Code review: finding the closest point on a surface

Posted by Doug Hull,

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 the problem exactly with computational geometry techniques. if (typeof(playerLoaded) === ‘undefined’) {var playerLoaded = false;}(function isVideojsDefined()… read more >>

Integrating to find the volume underneath a set of nonuniformly spaced data 13

Posted by Doug Hull,

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 numeric quadrature function is invoked. This video shows the creation of a good synthetic data set… read more >>
