问题 Arguments that are passed to a bash script can be passed on to a MATLAB function in the following way: #!/bin/bash matlab -nodesktop -nosplash -nodisplay -r "my_function('$1','$2')" But how to do this if I do not know the number of arguments to pass a priori? So I want to do something like this: #!/bin/bash matlab -nodesktop -nosplash -nodisplay -r "my_function('$1',...,'$N')" where I do not know what number N equals to a priori. I figure that you could create a string with a for loop

问题 I have an application where I'm building a function, marshal_and_apply , which calls some other function (or functor), f with some arguments. marshal_and_apply 's job is to apply some special marshaling for the arguments depending on the type of f 's parameters. If one of f 's parameters is of a special type, marshal_me<T> , then marshal_and_apply will marshal the parameter through some specially allocated storage before passing it to f . In order to perform the allocation, the storage

问题 SEE UPDATE for evolution of this question On my website, each user has a dashboard where s/he can click a link to either ACCEPT or DECLINE an request. Depending on what is clicked, the Request record is then PATCHed with the relevant status. To make it easier for users, I'm trying to embed this dashboard in an email to them so that they never have to go to the website directly; think of an email that looks like this: Hi there, You have the following requests, click ACCEPT/DECLINE next to the

问题 As it might be clear from the title which approach should we prefer? Intention is to pass a few method parameters and get something as output. We can pass another parameter and method will update it and method need not to return anything now, method will just update output variable and it will be reflected to the caller. I am just trying to frame the question through this example. List<String> result = new ArrayList<String>(); for (int i = 0; i < SOME_NUMBER_N; i++) { fun(SOME_COLLECTION.get

问题 Many people say that in Python arguments to functions are passed using a call-by-value model. As I understand it, it is not actually a call-by-value language, but a call-by-object or call-by-sharing model. What are the differences between a call-by-value model and a call-by-object model? What is an example in Python that shows how these models are different? 回答1: Saying that it is not pass-by-value is not correct. Semantically, it is pass-by-value, and one can demonstrate the semantic

问题 I apologize in advance if this has already been answered. I've Googled around for a few hours now, and I still haven't found anything that seems to answer my exact question. Essentially, I have a very complex/highly styled view which is displaying user-specific data pulled from the database. I've captured the data as a JSON object, attached it to the body my page using .data(). I've added a button that retrieves the JSON object and opens my printer friendly page in a new window. I want to be

问题 I have a Hudson job that execute shell script on a remote server. Its shell command is: /usr/bin/deployWar.sh ${warfileName} I marked this build as parameterized, and added a string parameter: name: warFileName default value: none description: name of war file When I run it, the parameter gets assigned, but it get passed into the shell script. 回答1: Parameterized Build Jenkins plugin documentation states that all the environment variables added by parameters are in upper case In your case this

问题 I have the following function working as I expect, in iOS 8: func showConfirmBox(msg:String, title:String, firstBtnStr:String, secondBtnStr:String, caller:UIViewController) { let userPopUp = UIAlertController(title:title, message:msg, preferredStyle:UIAlertControllerStyle.Alert) userPopUp.addAction(UIAlertAction(title:firstBtnStr, style:UIAlertActionStyle.Default, handler:{action in})) userPopUp.addAction(UIAlertAction(title:secondBtnStr, style:UIAlertActionStyle.Default, handler:{action in})

问题 Here's an example of where I started mylist = [["1", "apple"], ["2", "banana"], ["3", "carrot"]] def testfun(passedvariable): for row in passedvariable: row.append("Something else") return "Other answer" otheranswer = testfun(mylist) print mylist I'd expected mylist not to have changed. I then tried this to remove that temporary column, but that didn't work: mylist = [["1", "apple"], ["2", "banana"], ["3", "carrot"]] def testfun(passedvariable): for row in passedvariable: row.append(
