The easiest way is to use the "diary" function:
It will create a log file that contains keyboard input and result output. You can also customize the name for the output file. For example, to write into "myDiaryFile", execute:
diary myDiaryFile
a = 1;
b = sin(a);
x = ones(4)
diary off
Please note that the content in the command window might not be written into the log file right away. You can force the writing by toggling the switch for "diary" function. Example code:
diary on
a = 2 % Output of this line might not be written to file right away
diary off % until this command is executed
diary on % You could put diary 'on' if you want to log more command window output
a = 3
diary off

Sorry, I answer myself, which is not good. But my intention is to help people who may have similar problem.
When using non linear regression fit, the model mdl is displayed in the command window, with showing a table, with headers in bold characters. However, if like me, you use the command window and diary function to record the status of your running program, then the text file of the diary will display those bold character with the html code, which is not elegant. So it is possible to remove the bold character by using this function : formattedDisplayText(mdl,"SuppressMarkup",true)
function section(texte)
str_section = "*************************************";
disp(newline+ str_section + newline + texte + newline + str_section);
Once again, I sorry for answering my own questions, but I asked the question several weeks ago, and in between I continued my effort to find a solution, then I share it.

"diary" will also record command window text to a file. Try this:
>>diary on
>>"hello there"
>>diary off
A file will be created in your current directory with the text.

diary_name = strcat(datestr(now),'_diary.txt');
diary_folder = pwd;
diary off
(I am not sure diary off will stop the currently running diary(diary_name) ...)
It will be nice to write like this :
diary(diary_folder, diary_name,'on')
