How could I read a single cell of an .csv file using readmatrix function with import options?

Hello to everyone, I need to process different data from a .csv file. I do ask for the user what are the row ranges that need to read the code, with that, I need to save a value from a particular cell from the spreadsheet.

Next work very well for me. But I would like to know if it's possible to make this using import options.

kappa = readmatrix('1_5B_2.csv', 'Range', 'D6:D6');

Thanks in advance.

"possible to make this using import options."

Not sure what you mean here...explain more in detail.

Try this link to know the what import options you have for the file being read.

Then you can use either readtable to readmatrix with possible import options.

Thank you, it was a pretty simple solution.

First I did use detectImportOptions, searching the variable name (column), then I defined the data line range (row). In my case, it would be only using the same row position on both sides. Something like the next code.

opts = detectImportOptions('1_5B_2.csv');

opts.SelectedVariableNames = ('Var4');
opts.DataLines = [range(1,1) range(1,1)];

kappa = readmatrix('1_5B_2.csv', opts);
