问题

I tested following function in Scilab 6.1 and 2023.1. I try to read all *.txt files in a folder one by one and load it to a matrix.

datfiles=ls('*.txt','r');// List all *.txt Files in datfiles
for i = 1:size(datfiles, 1) // for each *.txt file
    token=strtok(datfiles(i,:),'.'); // save name of each txt.file and... 

    // execstr(token + '=csvRead('+ string(datfiles(i,:)) + ', ascii(9), [], ''string'')'); // use the name of the .txt file as variable name, where as all data is saved.

    execstr('csvRead('+ string("StepPo135.txt")+')'); //
end

I still get following error. By the way. How can I change this output to English? My preferences are set to English.

In line 1 of executed string

Attempt to reference a field in a non-structured array.

Error: Try, reference one field in not a structured array

datfiles=ls('*.txt','r');// List all *.txt Files in datfiles
for i = 1:size(datfiles, 1) // for each *.txt file
    token=strtok(datfiles(i,:),'.'); // save name of each txt.file and... 
    
    // execstr(token + '=csvRead('+ string(datfiles(i,:)) + ', ascii(9), [], ''string'')'); // use the name of the .txt file as variable name, where as all data is saved.
    
    execstr('csvRead('+ string("StepPo135.txt")+')'); //
end

这是解决方案：

datfiles = ls('*.txt'); // 列出所有 *.txt 文件在 datfiles 中
for i = 1:size(datfiles, 1) // 对于每个 *.txt 文件
    token = strtok(datfiles(i,:), '.'); // 保存每个 txt 文件的名称并...
    execstr(token + "=csvRead(" + "\"" + datfiles(i,:) + "\"" + ", ascii(9), [], 'string')"); 
end

datfiles=ls('*.txt');// List all *.txt Files in datfiles
for i = 1:size(datfiles, 1) // for each *.txt file
    token=strtok(datfiles(i,:),'.'); // save name of each txt.file and... 
    execstr(token+"=csvRead("""+datfiles(i,:)+""", ascii(9), [], ''string'')"); 
end

你需要通过加倍引号或双引号来添加引号，就像这样

execstr("token=csvRead("""+datfile+""")")```
错误消息是因为Scilab试图解释`StepPo135.txt`而没有引号，也就是说，它尝试提取`StepPo135`作为结构体的`txt`字段。

You need to add quotes or double quotes by doubling them, like this

datfile="StepPo135.txt";
execstr("token=csvRead("""+datfile+""")")

The error message is due to Scilab trying to interpret `StepPo135.txt` without the quotes, i.e. as if you were trying to extract the `txt` field of `StepPo135` considered as a struct.
