data = readtable('data.csv', 'ReadRowNames', true); 其他用法: 1. readtable函数可以读取文本文件中的表格数据,其中各列之间使用空格或制表符分隔。 data = readtable('data.txt', 'Delimiter', ' '); 2. 如果读取的表格数据具有日期和时间列,可以使用'VariableTypes'参数来指定这些列的数据类型。 3....

使用readtable函数通过默认设置创建表。用户还可以使用readtable函数将Excel表格转换为表。readtable函数可以处理具有分隔符的后缀为txt、dat或csv的文本文件,也可以处理后缀为xls和xlsx的表格文件。 >> T = readtable('patients.dat'); 查看表的尺寸信息: >> size(T) ans = 100 10 从结果可以看出,表T包含了10...

My best guess is that there's something installed on the path that conflicts with a function//variable that readtable is using internally. I am basing that on the fact that this doesn't seem to be happening with every user. One way to test this, is to make sure you're using only th...

使用readtable读取制表符分隔的句子对。指定德语文本作为源,英语文本作为目标。 filename = fullfile(dataFolder,"deu.txt"); opts = delimitedTextImportOptions(... Delimiter="\t", ... VariableNames=["Target" "Source" "License"], ... SelectedVariableNames=["Source" "Target"], ... Variable...
Possibly. If you use detectImportOptions, you can specify which variables to read in. For example, inthis examplethe following option is specified: opts.SelectedVariableNames = {'Systolic','Diastolic'}; You do not have to use variable names. You can also specify the columns by number. ...
