fprintf不打印新行 [英] fprintf not printing new line

问题描述

我试图使用 fprintf（）命令将[2 x N]大的数组发送到文本文件。我遇到的问题是： fprintf（）不能识别新的命令行（ \\\
），返回命令（ \r ）。我正在使用的代码是

$ $ p $ $ $ $ c $ fid = fopen（[Image.Dir，'CtlPts _'，Image.Files {k}， '.txt文件 ']，' W'）;
fprintf（fid，'％。4f\t％.4f\\\
'，control_points {k}）;
fclose（fid）;

其中我要打印的数据位于单元格 control_points {k } 。

标签打印正常，但文本文件中的所有内容都打印在一行上，所以这就是为什么我假设它是忽略我的新行字符。

我的语法有什么问题，我没有看到？

I am trying to send an array that is [2 x N] doubles large to a text file using the fprintf() command. I am having problems in that fprintf() is not recognizing the new line command (\n) or the carriage return command (\r). The code I am using is

fid = fopen([Image.Dir,'CtlPts_',Image.Files{k},'.txt'],'w');
fprintf(fid,'%.4f\t%.4f\n',control_points{k});
fclose(fid);

where the data I am trying to print is in the cell control_points{k}.

The tab gets printed fine, but everything in the text file gets printed on one line, so this is why I am assuming that it is ignoring my new line character.

Is there something wrong with my syntax that I am not seeing?

解决方案

I know that on many systems, \n is not enough to create what you're asking for (and so, maybe you have to do \r\n)
