I have csv file named as '1_1.csv', '1_2.csv', ...'1_41'.csv, '2_1.csv', '2_2.csv', ..'2_41.csv',............'71_1.csv', '71_2.csv',......'71_41.csv'. Each csv file has a data of temperature for different location (X ,Y, Z ,T). Each csv file has different number of rows because result is generated from comsol. I want to estimate temperature on specific point in each csv file. I have made another folder named "DATA" which contains my specific point(X, Y ,Z) in which i want to estimate temperature in each csv file. It is possible that our specific point may not be in csv file so i need to find temperature on that point with the help of interpolation.
I was using the code given below to get my temperature profile.
XYZq = csvread("DATA.csv");
num1s = 1:71;
num2s = 1:41;
T_interp = nan(size(XYZq,1),numel(num1s),numel(num2s)) % 3 dimensions
for num1 = num1s
for num2 = num2s
dataFilename = sprintf("%d_%d.csv",num1,num2)
data = csvread(dataFilename,9)
T_data = scatteredInterpolant(data(:,1:3),data(:,4));
T_interp(:,num1,num2) = T_data(XYZq);
end
end
now file name changes as '1_1_1.csv', '1_1_2.csv', ...'1_1_11'.csv, '1_2_1.csv', '1_2_2.csv', ..'1_2_11.csv',............'1_9_11.csv', '21_1_1.csv', '21_1_2.csv',.. '21_1_11.csv', '21_2_1.csv', '21_2_2.csv', '21_2_11.csv'.......'21_9_1.csv', '21_9_2.csv', .... '21_9_11.csv'.
now how can i modify this code to get my desire data? Please help me

csvFiles = dir('*.csv') ;
N = length(csvFiles) ;
for i = 1:N
csvFile = csvFiles(i).name ;
% read the file and do what you want
end
