Question

我需要一些帮助在MATLAB中读取.dat文件（作为数组）。

文件的内容（如果我用记事本打开它）就像这样

    public class NoLoopSort {
        static int[] values = new int[] { 4, 2, 5, 1, 3 };
        public static void main(String[] args) {
            printLower(0, values.length - 1);
            printLower(0, values.length - 1);
            printLower(0, values.length - 1);
            printLower(0, values.length - 1);
            printLower(0, values.length - 1);
        }

        private static void printLower(int start, int end) {
            if (start == end) {
                // this is currently the lowest number in array, print it.
                System.out.println(values[start]);
                // make current index biggest possible
                values[start] = Integer.MAX_VALUE; 
            } else {
                if (values[start] < values[end]) {
                    printLower(start, end - 1);
                } else if (values[start] >= values[end]) {
                    printLower(start + 1, end);
                }
            }
        }
    }

下面还有更多的线路，我真的不需要前几个线路。我只需要有数字在他们的牢房里。当我使用Excel或Libre Office打开文件时，它将打开，不带逗号或引号等。

阅读文件的最佳方法是什么？我找到了一些方法，但我遗漏了一些让它正常工作的东西：

我收到此错误：

f= fopen('x.dat');
data=fread(f);
fclose(f);`

y = importdata('x.csv') %I converted my .dat to a .csv and that worked well, but I really need it to read from the .dat file

fIDF=fopen(nameFile);
NephtDataAr0= textscan(fIDF, '%s %f %f %f %f %f %f %f %f %f %f %f %s %s','Delimiter',',','CommentStyle','[');
fclose(fIDF); 
%Someone that has written a program to read some similar data from a .txt file, used the line above. Could that be of any use?

filename = 'csvlist.dat';
M = csvread(filename)

我建议使用Readtable，请查看：
