function

问题 I am running a big m-file that I didn't write myself and that depends on certain subfunctions. I want to know if anywhere in all nested functions a particular function (in my case the function eig.m (to calculate eigenvalues) ) is used. Is there a quick way to do this? kind regards, Koen 回答1: You can use the semi-documented function getcallinfo (see Yair Altman's blog for more information about it): getcallinfo Returns called functions and their first and last lines This function is

问题 A function is returning an anonymous function. I would like to assign the result to a variable. However the compiler thinks that I am trying to assign the function and not the result of the function. How can I resolve this? program Project9; {$APPTYPE CONSOLE} type TMyEvent = reference to function: string; var v1: TMyEvent; function GetHandler: TMyEvent; begin Result := function: string begin Result := ''; end; end; begin v1 := GetHandler; // <- Incompatible types: 'TMyEvent' and 'Procedure'

问题 So one of the prompt of my lab is: "Find the percentage of vowels and percentage consonants in the English language. You should get a percentage of vowels = 37.4% and consonants = 62.5%." Here is just my percentage function. I think there may be something wrong with the for loops but I can't seem to figure it out.. Thanks for the help! int pv(string w) { double numC=0; double numV=0; string fName; ifstream inFile; double pc; cout << "Enter file name of dictionary (Mac users type in full path)

问题 I've this list of sequences aqi_range and a dataframe df : aqi_range = list(0:50,51:100,101:250) df PM10_mean PM10_min PM10_max PM2.5_mean PM2.5_min PM2.5_max 1 85.6 3 264 75.7 3 240 2 105. 6 243 76.4 3 191 3 95.8 19 287 48.4 8 134 4 85.5 50 166 64.8 32 103 5 55.9 24 117 46.7 19 77 6 37.5 6 116 31.3 3 87 7 26 5 69 15.5 3 49 8 82.3 34 169 49.6 25 120 9 170 68 272 133 67 201 10 254 189 323 226 173 269 Now I've created these two pretty simple functions that i want to apply to this dataframe to

问题 I've posted this before, but I'm reposting it with more detailed information. This is my assignment: And, so far, this is my code: # Define a function that caculates average test scores def calculate_average(score1, score2, score3, score4, score5): total = score1 + score2 + score3 + score4 + score5 average = total % 5 print(average) # Define a function that determines a letter grade # Based on the given score def determine_grade(score): if score < 60: print 'F' elif score => 60 or score <= 69

问题 C++ standard section 3.6.1/3 says that The linkage of main is implementation-defined What does it mean? Why it is implementation defined? Is it same in C also? 回答1: The purpose of C++ is to provide a portable abstraction over programming. Many things are specified by the standard so as to be unambiguous regardless of whether you translate your C++ to assembly, JavaScript, cheese, frying pans or supermodels. The linkage of main is not one of those things, because it is a bit of an abstraction
