I want to write a script that will look in a model for blocks of a particular type, a subsystem I made, and analyze the values passed to it as dialog parameters. I do not want this script to be an initialization callback<\/a>, I just want the users to be able to run it whenever they want, like a Model Advisor check<\/a>.<\/p>\r\n\r\n When my block is at the top of a model, it is very easy. Let's say I have variables \"a\" and \"b\" defined in the base workspace with respective values of 2 and 3. If the user specifies \"a+b\" as value of parameter \"c\" in my block, I can get the final value of \"c\" using the code below:<\/p>\r\n\r\n But what if the user puts my block inside another subsystem:<\/p>\r\n\r\n In this case, \"a\" and \"b\" are not in the base workspace anymore, they are in the mask workspace of subsystem SS_Level1.<\/p>\r\n\r\n The Solution<\/strong><\/p>\r\n\r\n If you look carefully at the bottom of the reference page for Mask Parameters<\/a>, you will find one named maskWSVariables<\/tt><\/p>\r\n\r\n Now it's your turn<\/strong><\/p>\r\n\r\n Let us know what you think of this technique, or if you have preferred tricks to access values and properties in a model by leaving a comment here<\/a>.<\/p>","protected":false},"excerpt":{"rendered":" Today I want to share a trick I recently found out.\r\n\r\nThe Problem: Getting the Value of Nested Mask Parameters\r\n\r\nI want to write a script that will look in a model for blocks of a particular type,... read more >><\/a><\/p>","protected":false},"author":41,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[15,47,69],"tags":[437],"_links":{"self":[{"href":"https:\/\/blogs.mathworks.com\/simulink\/wp-json\/wp\/v2\/posts\/4743"}],"collection":[{"href":"https:\/\/blogs.mathworks.com\/simulink\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/blogs.mathworks.com\/simulink\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/blogs.mathworks.com\/simulink\/wp-json\/wp\/v2\/users\/41"}],"replies":[{"embeddable":true,"href":"https:\/\/blogs.mathworks.com\/simulink\/wp-json\/wp\/v2\/comments?post=4743"}],"version-history":[{"count":7,"href":"https:\/\/blogs.mathworks.com\/simulink\/wp-json\/wp\/v2\/posts\/4743\/revisions"}],"predecessor-version":[{"id":4750,"href":"https:\/\/blogs.mathworks.com\/simulink\/wp-json\/wp\/v2\/posts\/4743\/revisions\/4750"}],"wp:attachment":[{"href":"https:\/\/blogs.mathworks.com\/simulink\/wp-json\/wp\/v2\/media?parent=4743"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/blogs.mathworks.com\/simulink\/wp-json\/wp\/v2\/categories?post=4743"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/blogs.mathworks.com\/simulink\/wp-json\/wp\/v2\/tags?post=4743"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"Example](\"https:\/\/blogs.mathworks.com\/images\/seth\/2015Q3\/justOneblock.png\")

<\/p>\r\n\r\nThis parameter will return an array of structures with fields Name<\/tt> and Value<\/tt> for each parameter of your mask. Once I have it, I like using a containers.Map<\/a> object to access the parameter values easily.
