Hi,

Id like to read a notepad file row and make that into a variable

txt{6}(1:end-1)=File(cals,txt{6}(1:end-1)); (says Conversion to char from struct is not possible)

I can run this command: txt{6}(1:end-1) and it would give me, ans="x"

i can also run A=File(cals,txt{6}(1:end-1)); and it would output a 1 by 1 structure with a value inside it.

Any suggetions?

Do i need to use eval? etc

Thank you!

在 MATLAB Online 中打开

% Specify the path to the text file
filePath = 'path/to/your/file.txt';
% Read the text file
fileData = fileread(filePath);
% Split the file contents by newline character to get individual rows
rows = split(fileData, '\n');
% Select the desired row (in this example, row number 6)
rowIndex = 6;
selectedRow = rows{rowIndex};
% Display the selected row
disp(selectedRow);
% Store the selected row in a variable
myVariable = selectedRow;
