You reference elements like this:
Given any matrix
M=[a1,a2,a3,...,an;
.
.
.
m1,m2,m3,...,mn]
an element is accessed by referenceing its row and column position. So,
M(c,10) would return the element loacted in the third row, 10th column.
MATLAB is balking at taking the inverse function of E. Your elements of E don't work. NaN means Not A Number and that is showing up because the inverse of your E matrix is infinity thus a matrix times infinity yields NaN.
mod is the modulus of command. A modulus is essentially the remainder of a division process. Here's a few examples:
4/2=2 R=0--2 goes evenly into 4 thus there is no remainder.
so, mod(4,2) would give a result of 0
9/4=2 R=1--4 goes into 9 twice leaving a remainder of 1
so...
ARGH! Matlab trouble!
Ok, I'm having a big problem as described here: https://www.physicsforums.com/showthread.php?t=46950
Basically, I've never used MATLAB and was given an assignment on friday which requires that I use matlab. First off, could someone please help me with my projectile...

Linux: Distro CD is easiest source
Mac OS: There's a link to the i-Installer
It's easy to use once you learn how. It's quick and efficient.
Good starting points:

I've used LaTeX a bit more than the average person I'd say. I'm not a professional typesetter by any means but I can put some good looking stuff together with the help of LaTeX. If you can type fast the LaTeX is definately the fastest way to put together a good report. Typing {\bf yadda yadda...
Ohhh, linear algebra notes huh?
Add this line somewhere before your \begin{document}: \newtheorem{eqn}{Equation}[section] You probably have a two or three line block below the page layout section and prior to the title section if you're using a latex template (that's where I've seen it with...
You can't. You can surpress sections and use subsections to number 1.3, 1.4, ... 1.n like this:
\begin{document}
\setcounter{section}{1}
\section*{}
\setcounter{subsection}{2}
\subsection{Label this}
\end{document}
You need to use subsections to append the numbering after the initial...
If I'm reading your question correctly then this should have worked:
\begin{document}
\section{Some Section}
\setcounter{subsection}{2}
\subsection{Some subsection starting at 1.3}
\end{document}
Are you using subsections?
\setcounter{subsection}{2}
the 1 comes from the section tag
the .3 comes from the subsection tag
if you set the subsection couter to 2 then then next time you use the subsection tag it will display as three. I'm sure there's another way to do it, but I've always used the above.
Good...
