Hi,
See my script below, I need to add the changing variable 'num' as title name. How can i fix that?
for i = 3:3
num = subFolders(i).name
num2 = struct2cell(num)
folder = ['C:\Users\dit\Documents\MATLAB\RawData\',num]; f = dir(fullfile(folder,'*.csv')); g = numel(f);
figure
title('How can I add num here?')
for k = 1:g
filename = fullfile(f(k).folder, f(k).name);
CSVData = readmatrix(filename, 'Range', 1, 'Delimiter', ','); [filepath,name,ext] = fileparts(filename); indexCSV = [(0:size(CSVData,1)-1)' CSVData];
xC{k,1}=CSVData(:,7); yC{k,1}=CSVData(:,8); zC{k,1}=CSVData(:,9); radC{k,1}=CSVData(:,2)/2;
indexC =indexCSV(:,1); [valCL, idxCL] = max(indexC);
plot3(xC{k,1},yC{k,1},zC{k,1},'-b')
hold on
end
folder = ['C:\Users\dit\Documents\MATLAB\Centerlines_Python\',num]; f = dir(fullfile(folder,'*.txt')); g = numel(f)-1;
for i = 0:g
Ofilename = fullfile(f(i+1).folder, f(i+1).name);
DataText=load(Ofilename);
x = DataText(:,1); y = DataText(:,2); z = DataText(:,3);
plot3(x,y,z,'-')
hold on
end
pause
close
end

Since ‘num’ should be a simple character vector (at least it is when I tested this in R2020b), one of these should work:
title(num) % Includes Extension
title(extractBefore(num,'.')) % Removes Extension
.
