In the video, we will make a function out of the formula.  The function will take a scalar (single number) or a vector.  We want to make the function take either a scalar or a vector so that you do not have to loop through calling the function.  This is not for speed, but for the simplicity and readability of the code.  This vectorization is done by means of array division ( .\/ ) and array multiplication ( .* ).  These operations do division and multiplication on an element by element basis.\r\n\r\n<div><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=\"3877437983001\" 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>\r\n <\/div>\r\n\r\n","protected":false},"excerpt":{"rendered":"<div class=\"thumbnail thumbnail_asset asset_overlay video\"><a href=\"https:\/\/blogs.mathworks.com\/videos\/2009\/08\/27\/basics-implementing-a-formula-in-matlab\/?dir=autoplay\"><img decoding=\"async\" src=\"https:\/\/cf-images.us-east-1.prod.boltdns.net\/v1\/static\/62009828001\/09f65176-3ad8-4e6b-a40e-09fe36b20e70\/4889de28-20a7-4347-b194-9eb31b5bc14e\/1280x720\/match\/image.jpg\" onError=\"this.style.display ='none';\"\/>\n      <div class=\"overlay_container\">\n      <span class=\"icon-video icon_color_null\"><time class=\"video_length\">4:59<\/time><\/span>\n      <\/div>\n      <\/a><\/div><p>This video will demonstrate how to implement a formula in MATLAB.
