Can you please say why this is coming? can you please solve this?

function [Sample,Status,P0,RawP,RawT]=extract_data_P0(Nomfichier,SW_version)
%2 variable input 5 out put

opts=detectImportOptions('Capteur2125011.txt');
opts.DataLine=7;
opts.VariableNames={'SampleNumber','ReceivedFrame'};
RawData=(readtable(Nomfichier,opts));
Sample=table2array(RawData(:,1));
RawFrame=table2array(RawData(:,2));
%This code extracts data from a text file and converts it into two arrays
for i=1:length(RawFrame)
    Status(i,1)=hex2dec(cat(2,RawFrame{i}(7:8),RawFrame{i}(10:11)));
    P0(i,1)=hex2dec(cat(2,RawFrame{i}(19:20),RawFrame{i}(22:23)));

Error:

Error in extract_data_P0 (line 7)

RawData=(readtable(Nomfichier,opts));

[Walter Roberson]

you show where the error is but you do not show what the error is.

My guess is that you tried to run this function by pressing the green Run button. When you use the Run button, that is the same thing as executing the function without any inputs, as if you had executed

extract_data_P0()

which would fail when it tried to use the Nomfichier variable.

You forgot to attach 'Capteur2125011.txt'. My guess is that you're either creating fields of "opts" that are not valid in readtable(), or you are not passing a string or character array in for Nomfichier, but we don't know because you also forgot to attach the actual error message (ALL THE RED TEXT, not just a snippet of it).

If you have any more questions, then attach your data and code to read it in with the paperclip icon after you read this:
