Hello,

Let's say I have multiple csv files that are named 'valuesx.csv' where x is a number between 0-99, so I have 100 csv files with similar names.

Is there a way to read all of the files into Matlab without having to use 'readtable' 100 times for each of the files. I was thinking that I could use a for-loop (or something similar) to read all of the files, but my problem is that I don't know how to make it read multiple files.

I was thinking something like this:

for x = 0:99
    readtable(valuesx);
end

I know that this code doesn't work, but I was thinking something like this.

Is there a way to make such a code or do I need to read each file separately with 'readtable'?

在 MATLAB Online 中打开

Something like this

for x = 0:99
    filename = sprintf("values%d.csv",x)
    tbl{x+1} = readtable(filename);
end

This will store each file in one cell of a cell array. Note that I had to offset the number of the cells, because MATLAB does not have 0-based indexing.
