Hello All,

With reference to this question : https://in.mathworks.com/matlabcentral/answers/444506-saving-array-values-as-mat-file

Thanks to awesome people here, I could manage to cleanup my .csv files and could save them as .mat with following code:

clearvars
close all
clc
d = uigetdir();
filePattern = fullfile(d, '*.csv');
file = dir(filePattern);
x = cell(1, numel(file));
for k = 1 : numel(file) 
      baseFileName = file(k).name;
      fullFileName = fullfile(d, baseFileName);
      [filepath,name,ext] = fileparts(fullFileName);
      x{k} = readtable(fullFileName);
      fprintf('read file %s\n', fullFileName);
      %fprintf('read file %s\n', baseFileName);
      %writetable(x{k},fullFileName);
      temp = table2struct(x{k}(3:end,:),'ToScalar',true);
      save([name '.mat'],'-struct','temp')
end

Now the mat file is being created with cell array of column headers inside the .csv file. What I want is instead of cell arrays, I want to have it as matrix. I have preprogramed tool which plots the .mat arrays but these being cell arrays, I suspect that tool is not working.

your help is much appreciated
