Hello all, I am trying to run a matlab script for a dataset. For this I have to change the script for each data file. For example below is my script and my datasets goes from data 1 till data 40. I want to automate this and get all the graphs at one time. Is this possible and how can I do this? Thank you in advance.
load data40 ; %%change the number after data into the desired data
frequency = data40(:,1); %%name the variable 1st collumn to frequency
zabsolute = data40(:,2); %%name the variable 2nd collumn to zabsolute
degree = data40 (:,3); %%name the variable 3rd collumn to degree
x= frequency * 1000; %% frequency is given in KHz multiply with 1000
y1 = zabsolute .* cosd(degree); %% formula to calculate the imaginair component of impedance
y2 = zabsolute .* sind(degree); %% formula to calculate the real component of impedance
subplot(2,1,1);
plot(x,y1),
title ( ' Resistance ' );
xlabel ( ' Frequency (Hz)');
ylabel ( ' Re Z');
subplot (2,1,2);
plot (x,y2);
title ( ' Reactance' );
xlabel ( ' Frequency (Hz)');
ylabel ( ' Img Z')

matFiles = dir('*.mat') ;
N = length(matFiles) ;
for i = 1:N
load(matFiles(i).name) ; % you need to see how the variables are named here
frequency = data(:,1);
zabsolute = data(:,2);
degree = data(:,3);
x= frequency * 1000; %% frequency is given in KHz multiply with 1000
y1 = zabsolute .* cosd(degree); %% formula to calculate the imaginair component of impedance
y2 = zabsolute .* sind(degree); %% formula to calculate the real component of impedance
figure(i)
subplot(2,1,1);
plot(x,y1),
title ( ' Resistance ' );
xlabel ( ' Frequency (Hz)');
ylabel ( ' Re Z');
subplot (2,1,2);
plot (x,y2);
title ( ' Reactance' );
xlabel ( ' Frequency (Hz)');
ylabel ( ' Img Z')
end

I suffer some problems with the code with the dir I copy my pathway and past it inside the function
as dir('/Users/Bayram/Desktop/Master Project/naamloze map\*.doc')
it gives me the error' No matches for pattern '/Users/Bayram/Desktop/Master Project/naamloze map\*.doc'.'
and when I try to run the the script you gave me I can't get anything.
The problem that I think I have is that the files that I have do not have .doc or anything else. It is just named as data1. It all is a document file. I do not know if that matters?
