1. Purpose of matlab@trinitas.mju.ac.kr     [ 한글 설명 ]
Automatic execution of sender-provided reduce comands between 
     input:      and      end input:   
and return of the results to the e-mail sender.

2. Introduction
A User Application Package, Matlab is available via our InetCompu Service.  In particular, this will help a lot those having difficulties in basic symbolic and numerical computations such as in calculus, linear algebra, and engineering mathematics, etc. 

3. Notes
3-1. No matlab commands requiring graphics treatments, for instances, plot, etc, will produce highly qualified visual results.
3-2. For a trouble-free handling of your e-mail, we strongly recommend you to use MicroSoft Outlook Express, New mail > Alt+O > Alt+X (with No Encryption),  to send out an e-mail to our InetCompu Service.  Otherwise, please read subsections 3-3 and 3-4  of intro2InetReduce.html.

4. How to do: Send an e-mail with plain text style (for instance, in the case of MicroSoft Outlook Express, New mail > Alt+O > Alt+X (with No Encryption)) to matlab@trinitas.mju.ac.kr whose main body should consist of, for example,

     input: 
         format long
         s=0; x=0.5; n=1;
         while (x^n)/n >= 10^(-10),
                    s=s+((-1)^(n+1))*((x^n)/n);
                    n=n+1;
          end, n, s
     end input:

which computes the approximated value of Maclaurin series of ln(x+1) at x=0.5 until the absolute value of the last term is less than or equal to 10^(-10). 

Then upon the arrival of the e-mail, the commands between input: and end input: are executed automatically and the results are sent back to the e-mail sender immediately. The sender will also get the timex report on execution time by our Server at the end of the returning e-mail.

Remark. If one wants to know more about maple commands, then send, for instance

     input: help                           or

     input:
     help
     end input:

to matlab@trinitas.mju.ac.kr   .

[Reminder] When the requested job is computationally not very complicated, it should be quite the case that you will receive the result within a few Minutes.  But, our response consisting of the computed results can not be delivered to the sender properly, if either there is a spelling mistake in sender's e-mail address or sender's mail box is already filled with too many of other e-mails. Thus, if you do not receive the results although you have waited for some time, then please check your mail account to correct the above trouble-causing problems.  After that, try agin according to the procedure described in Section 4 above.
