Typically my functions are &#8220;old school&#8221; where parameters need to be in certain positions. I use <tt>varargin<\/tt> for optional additional parameters, followed by some logic to set default values should later parameters not be present.<\/p>\n<p>Currently I have a function which already has a few parameters, and I want to add more. With positional parameters, you have to supply all the ones up to the one you need which can get cumbersome if there are many. So I thought I would try using <tt>inputparser<\/tt> and make some of the parameters name-value pairs. This will give more flexibility in allowing only certain parameters to be specified.<\/p>\n<p>Features covered in this <a href=\"https:\/\/blogs.mathworks.com\/videos\/2015\/10\/29\/matlab-code-along-videos\/\">code-along<\/a> style video include:<\/p>\n<ul>\n<li><tt><a href=\"https:\/\/www.mathworks.com\/help\/matlab\/ref\/inputparser.html\">inputparser<\/a><\/tt><\/li>\n<\/ul>\n<p><div class=\"row\"><div class=\"col-xs-12 containing-block\"><div class=\"bc-outer-container add_margin_20\"><videoplayer><div class=\"video-js-container\"><video data-video-id=\"5980454312001\" data-video-category=\"blog\" data-autostart=\"false\" data-account=\"62009828001\" data-omniture-account=\"mathwgbl\" data-player=\"rJ9XCz2Sx\" data-embed=\"default\" id=\"mathworks-brightcove-player\" class=\"video-js\" controls><\/video><script src=\"\/\/players.brightcove.net\/62009828001\/rJ9XCz2Sx_default\/index.min.js\"><\/script><script>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);}})();<\/script><\/div><\/videoplayer><\/div><\/div><\/div><\/p>\n<p>Play the video in full screen mode for a better viewing experience.\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<div class=\"thumbnail thumbnail_asset asset_overlay video\"><a href=\"https:\/\/blogs.mathworks.com\/videos\/2018\/12\/17\/trying-out-inputparser\/?dir=autoplay\"><img decoding=\"async\" src=\"https:\/\/cf-images.us-east-1.prod.boltdns.net\/v1\/static\/62009828001\/caefe71e-b4a7-4c91-a35d-a797e428dfe7\/46312ba5-5fdd-439e-8e99-a0993aa09be6\/1280x720\/match\/image.jpg\" onError=\"this.style.display ='none';\"\/><\/p>\n<div class=\"overlay_container\">\n      <span class=\"icon-video icon_color_null\"><time class=\"video_length\">20:51<\/time><\/span>\n      <\/div>\n<p>      <\/a><\/div>\n<p>I&#8217;m going to try to use inputparser for the first time, to specify name-value pair parameters for my function.<br \/>\nIts been around for several years but I haven&#8217;t used it.
