Extracting data file in workspace from a table/files

I have a folder (Measurement_1) of 120 data files in CSV format where each data file has the data of three sensors under name A, B, C). The final goal is to run the algorithm over each data file.

- I have started to import the data from the folder into matlab.

- Using the code

files = dir('*.csv');
tables = {};
for i = 1:length(files)
tables{i} = readtable(files(i).name);
end

I got three items in the work space

files 120x1 struct

i 120

tables 1x120 cell

Now, how can I extract the my 120 data recordings/files that are under different names such as

- sensors A, line_1

- sensor A, node_4

-sensor X, point_7X

.

.so on till 120

I am basic user of matlab, any help will be appreciated, many thanks.

The best thing is not to do that at all.

Hi Walter, if you are referring to differnt names; the data is obtained from already done measurements, I do not have the possibility ot change the data files' name :(

When you said,

Now, how can I extract the my 120 data recordings/files that are under different names such as
-  sensors A, line_1
- sensor A, node_4
-sensor X, point_7X

are things like "sensors A, line_1" the file names? Or are they the names of columns? Perhaps "sensor A, line_1" and "sensor A, node_4" are intended to refer to the same file "sensor A.xlsx" and you want to extract variables "line_1" and "node_4" from those?? How is it determined what will need to be extracted?

When I read your question, I thought what you were asking was to create workspace variables named after the files, so the content of "sensor A, line_1" would be expected to be stored into a variable named something like "sensor_A_line_1" . That is the sort of practice that is discouraged: creating workspace variables named according ot data content is not a good idea. But now looking back, I realize I do not understand what it is that you actually want to do with the data once it is read in ??

Just to mention that this issue is sloved now, thanks.
