Hello everyone,
I do not know why I cannot open this file in MatLab. Can anyone help me?
fileID = fopen('Test_Zugversuche_PDMS_Probe 10.8_charge3.TRA');
file_data = textscan(fileID,'%f64 %f64 %f64 %f64','Delimiter','; ','HeaderLines',8);
Error using textscan
Invalid file identifier. Use fopen to generate a valid file identifier.
Error in Young_Mod (line 56)
file_data = textscan(fileID,'%f64 %f64 %f64 %f64','Delimiter','; ','HeaderLines',8);

filename = 'Test_Zugversuche_PDMS_Probe 10.8_charge3.TRA';
[fileID, message] = fopen(filename, 'r');
if fileID < 0
error('Failed to open file "%s" because "%s"', filename, message);
end
My guess would be that the file is not in your current directory or anywhere along the MATLAB path.
