What is the mistake in this code ?

Error using importdata (line 139) Unable to open file.

Error in Capacity_Total_up_Output (line 19) C_Total{i} = importdata(fullfile(P,F_Total));

%The Two Files are C_Total_1.txt , C_Total_2.txt
clc;
clear;

N = (6:10).^2; %Number of Elements IRS
K = 2:2:10; %Number of Single Antennas UE

C_Total_1 = importdata('C_Total_1.txt') ; % Total Capacity 
C_Total_2 = importdata('C_Total_2.txt') ; % Total Capacity 


P = 'C:\Users\tripo\Documents\Total_April_Capacity\ART';
Total_File = [1,2];
Total_Capacity_File = numel(Total_File);
C_Total = cell(1,Total_Capacity_File);

    F_Total = sprintf('C_Total_%d.txt',Total_File(i));
%     C_Total{i} = importdata(fullfile(P,F_Total));

Can you also post the error message that you see? And the input file you are reading, or a sample of it?

How could we possibly know without the two files, C_Total_1.txt , C_Total_2.txt, that you forgot to attach? Please attach them after reading this:

All I can guess is that the file is not in the current folder or on the search path.

I modified your code to be able to run here. There is no error message, and the plots appear. The most likely reason for your error is what ImageAnalyst said: your files were not in the path you specified: C:\Users\tripo\Documents\Total_April_Capacity\ART

Double check your path.
