output

问题 Say I have a function whose outputs are two reals a and b [a,b]=function(c) I'd like to get all the outputs in a vector v. v=function(c) doesn't do what I want, v is 'a' only. Of course here I could do v=[a,b]. But the function in question is ind2sub for a N-D array so it gives n outputs that I'd like to have in a vector directly. Is there a way to do it? Thanks very much! 回答1: You can use a cell array and a comma-separated list like so: X = cell(N, 1); [X{:}] = function(C); The syntax X{:}

问题 I am working on an alternate screen feature for my cross-platform terminal manipulating crate. Situation When I want to write something to console I can use the following code to write to the current standard output. This works on both UNIX and Windows systems: write!(::std::fmt::io::stdout(), "Some text"). When I switch to the alternate screen, I don't want to write to the current standard output but to the alternate screen. This works differently depending on which platform you are on. The

问题 In C I use "1st line 1\n2nd line" for a newline, but what about VB? I know "1st line" & VbCrLf & "2nd line" but its too verbose, what is the escape char for a newline in VB? I want to print 1st line 2nd line I tried using \n but it always outputs this no matter how many times I run the compiler 1st line\n2nd line Any ideas? 回答1: You should use Environment.NewLine . That evaluates to CR+LF on Windows, and LF on Unix systems. There are no escape sequences for CR or LF characters in VB. And that

问题 I've been struggling with this problem for a long time now, but I cannot really find the solution. The problem is that < !DOCTYPE html etc... does not start at the first line, but leaves four blank lines before it starts.
