Now that you have actually shown some code, there is still a problem. The error message tells us that your file is not what you think it contains. But we have no idea what the file truly does contain.

Finally, you need to understand that posting a PICTURE of your code is not useful. That forces someone who might help you to ttype in your code from the screen.

Is there a good reason why you want to make it more difficult to get help? Paste in the actual code. Attach the file so that someone can understand what is inside the file that you could not read.

Book5 measured - Copy (2).csv

clear all; %#ok<CLALL>

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

A=dlmread('Book5 measured - Copy (2).csv');

x=A(:,1); % it contains frequency column

y=A(:,2); % it contains Peak gain for phi=0 and theta=90 coloumn which is 2nd column.

dlmread cannot handle the double quotes around the numbers. Use modern import functions instead, e.g. readmatrix(). The option 'TrimNonNumeric' might be useful.
