我无法在MATLAB中加载文本文件。我正在使用的代码是:
y=load('AllReadings.txt')
哪个会产生错误:
文本文件的内容为:
Heart Rate (BPM) GSR Respiration Rate Ambient Temperature
inf 495 49.96 3
inf 495 49.96 3
inf 495 23.03 7
inf 496 23.03 7
inf 495 23.03 7
inf 496 23.03 11
7.68 496 23.03 11
7.68 496 23.03 14
7.68 496 23.03 14
7.68 496 23.03 15
7.68 496 23.03 14
(编者注:使用制表符和空格的组合来分隔源数据,这在呈现的输出中不可见,但在编辑问题时可以看到。)

我在R2019a上对其进行了测试,可以使用importdata
正确导入这样的文本文件:
>> y = importdata('AllReadings.txt')
y =
struct with fields:
data: [11×4 double]
textdata: {'Heart Rate (BPM) GSR Respiration Rate Ambient Temperature'}
>> y.data
ans =
Inf 495.0000 49.9600 3.0000
Inf 495.0000 49.9600 3.0000
Inf 495.0000 23.0300 7.0000
Inf 496.0000 23.0300 7.0000
Inf 495.0000 23.0300 7.0000
Inf 496.0000 23.0300 11.0000
7.6800 496.0000 23.0300 11.0000
7.6800 496.0000 23.0300 14.0000
7.6800 496.0000 23.0300 14.0000
7.6800 496.0000 23.0300 15.0000
7.6800 496.0000 23.0300 14.0000

这是一个虚拟文件:
header1|header2|header3|header4
adfads|sjk|jkghj|jdauuy2
0987yuh|mnjkhuy6|nmbhgf|0987yuh
098iuhyj|4e5rtyguh|67tyughj|oijk
以及要导入的代码:
filename = 'dummy.txt';
nCols = 4;
delim = '|';
colFmt = repmat('%s',1,nCols);
fid = fopen(filename,'r');
header = textscan(fid, colFmt, 1, 'delimiter', delim);
dataArray = textscan(fid, colFmt, 'delimiter', delim);
fclose(fid);
dataArray = [dataArray{:}]; % this "unpacks" the cell
