Hello,
Hello, I am trying to import the values from a text file and create a plot from it. However, it is unable to read the txt file and when I check the variables, it shows the text file, but none of the variables. When I run the code, this shows up. Error using importdata (line 136) Unable to open file.
Error in 360_Hmk1 (line 5)
A1=importdata('0012data.txt',' ',2);"
I tried to convert my text file from a table to a cell array but this didn't work in that it didn't even show up as a variable. I appreciate your help. Thanks. Heres the code that I used:
if true
% code
end
%%Creating plot of airfoil cross section.
clear all;
% Import both data from txt. files
A1=importdata('0012data.txt',' ',2);
AF1x = A1.data(:,1);
AF1y = A1.data(:,2);
AF1Cp = A1.data(:,3);
plot(AF1x,AF1y,AF1Cp)
grid on;

I suspect that your current directory is not set to the directory that the file is in. Use the cd command to change current directory

Also there is a possibility that there is a hidden file extension. What does
ls 0012*
show?
