Any MATLAB pros out there?

leehkai45 — Wed, 17 Jun 2009 11:05:16 +0800

Hey all,

It will be really great if you could just help me with this one part.

I currently have a function [a = compare(input) which returns 2 output values, a and b when I input values from say, 1 to 30.

However, these values are in scalar form and not vectors, and I think it's best to put the output in a predefined vector before plotting it. However, I am not getting the plot for the graph. There is definitely a problem with the code in graph plotting and the function is fine.

Any ideas on how to code it if I want to plot 2 curves of a vs input and b vs input?

Also, how do I plot both a and b vs input on the same graph?

Thank you so much for your help!!

[addedon]June 17, 2009, 11:06 am[/addedon]The function above should be [ a b ] = compare(input)

Sorry for the unexpected smiley

help!

trojandownloader:win32/renos.io

any idea on how to remove it?
also, the windows security center just won't turn on, it says it can't be started and when i check everything on control panel, it seems fine. guess it might be the viruses in the computer which is stopping it from starting?

thanks in advance for the help!

Help needed for Acer laptop! :(

leehkai45 — Sat, 01 Nov 2008 00:32:40 +0800

Hey there, I currently have an Acer laptop which works really slow initially, and it keeps popping up that there are spywares in it. I've tried using Spybot S&D but it wouldn't load in the normal Windows mode and in safe mode. The laptop is really slow and I decided to ask a friend of mine to reformat it.

Apparently, whenever he's reformatting it, before it finishes the job, the computer will shut down immediately. Now that whenever I switch on the laptop, there's this "General Protection Fault" message which comes up (with a list of codes?) and it doesn't take me to Windows Desktop anymore! Can anyone help me on this issue?

Thanks in advance and your help is very much appreciated.

C++ experts, please help! =)

hey there! i'm given a C++ sudoku assignment and i have a vague idea of how to write or structure the code (I'll be writing the codes myself instead of taking it straight from the internet).. Requirements are as below:

Read a 9x9 sudoku from a file: e.g.

5 3 4 | 6 7 0 | 9 1 2
6 7 2 | 1 9 5 | 3 4 8
.
.
.

basically some cells do not have a specific value i.e. "0". I'm supposed to read the problem from the file and then output it to another file (basically calculate all possible solutions). Program should report if no solution exists.

Anyone has any idea on how to do it??

Thanks for your help!! =)

Problem with laptop speaker

leehkai45 — Thu, 22 Nov 2007 00:53:59 +0800

Hey guys, experiencing a rather awkward situation here.

Wondering if anyone ever experience the same problem before.

I'm currently on a Dell XPS M1330. This laptop is still rather new as I bought it last month. Initially when I received it, everything was working perfectly alright. However, now, its speakers died and I'm wondering if the problem is with Dell or there's other factors affecting it.

Has anyone on a M1330 ever experience the same problem?

Hey there, my friend seems to be having a slight problem here.

When she tries to log in to MSN Messenger, an error code of the following is observed:

Error Code: 80048820
Extended Error Code: 80048439

However, when I use my laptop to access the same wireless network, it could work on my side.

How is this possible? Does anyone know the reason why?

Thanks in advance!
