MATLAB - Read multiple *.log files, calculate and save as .*txt in new folder - matlab

Question

I make different measures and save it like *.log files, calculate it and save as .*txt.
%Filtering log files
l = dir('*.log');
%Array size detection
[rows cols] = size(l);
%Choose a last file
file_name = strcat(strcat(l(rows).folder,'/'),l(rows).name)
%Reading log last file
fileread = fopen(file_name);
%Convert to float
times = fread(fileread,'float32');
%Filtering times and set to 0 small values
times(times<1e-8)=0;
%Set right times values
times_s = times * 1.0e-06;
%Solve full rotation speed (Hz)
motorspeed_full = 1./(2.*times_s)
%Filtering inf values and set to 0
motorspeed_full(motorspeed_full>1e+10)=0;
%Solve half rotation speed (Hz)
motorspeed_half = 1./(times_s);
A = '.txt';
[filepath,name,ext] = fileparts(file_name);
Xfilename = cat(2,name,A);
dlmwrite(Xfilename,motorspeed_full,'precision','%.3f');
So, it's possible to choose a last file, calculating it and convert it to .*txt. So now, I have to make a calculation after every measure.
My aim is:
Making first 1...n measures (1...n - *.log's and wav's)
Calculating and saving 1...n *.log's to *.txt's (see picture)
Create folder with file_name (ex. 20181120_125713) and insert file_name.txt and file_name.wav into this folder structure
Questions:
How can I converting all *.log files to *.txt files using dlmwrite?
How can I create a new folder with file_name
mkdir(name);
for all files?
How to move the files with same names to folder with same name? Name of folder changes every time, so i can't work with
movefile source destination
Thank you very much for any help :*)

Answer 1

Here is my solution. Maybe it can help somebody:
clear all;
clc;
%Filtering log files
l = dir('*.log');
for k = 1:length(l)
next_name = l(k).name
%Array size detection
[rows cols] = size(l);
%Choose a last file
file_name = next_name;
%Reading log last file
fileread = fopen(file_name);
%Convert to float
times = fread(fileread,'float32');
%Filtering times and set to 0 small values
times(times<1e-8)=0;
%Set right times values
times_s = times * 1.0e-06;
%Solve full rotation speed (Hz)
motorspeed_full = 1./(2.*times_s);
%Filtering inf values and set to 0
motorspeed_full(motorspeed_full>1e+10)=0;
%Solve half rotation speed (Hz)
motorspeed_half = 1./(times_s);
A = '.txt';
[filepath,name,ext] = fileparts(file_name);
Xfilename = [name,A];
mkdir(name)
dlmwrite([name,filesep,Xfilename],motorspeed_full,'precision','%.3f');
% [name,'.wav'],[name, file, name, '.wav']
movefile([name,'.wav'],[name, filesep, name, '.wav']);
end
