\renewcommand{\thefigure}{\thechapter.\arabic{figure}}
^notice the period here!
This gives Figure numbers

3.12,...

if someone would like to change the figure numbering, it should be similar.

solve equation in matlab.

syms xr;
aa=0.84; % for the given spin value

ss=aa-(2/3)^0.5*xr*(4-(18*xr^2-2)^0.5);

yy=solve(ss);

mif=double(yy(2)); %%% convert the symbolic object into the real number.

@misc{
c.elmohamed,
%author = "Saleh Elmohamed",
%title = "Examples in {H}igh {P}erformance {F}ortran",
%howpublished = "Website",
%year = {1996},
note = {\url{http://www.npac.syr.edu/projects/

}


Example usage

In the preamble:


\usepackage{url}

%% Define a new 'leo' style for the package that will use a smaller font.
\makeatletter
\def\url@leostyle{%
\@ifundefined{selectfont}{\def\UrlFont{\sf}}{\def\UrlFont{\small\ttfamily}}}
\makeatother
%% Now actually use the newly defined style.
\urlstyle{leo}

In a BibTEX entry:


@misc{
c.elmohamed,
author = "Saleh Elmohamed",
title = "Examples in {H}igh {P}erformance {F}ortran",
howpublished = "Website",
year = {1996},
note = {\url{http://www.npac.syr.edu/projects/
cpsedu/summer98summary/ examples/hpf/hpf.html}}
}


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

please note there is no any comments inside the entry, e.g., the following example will not work


For science magazine, there are two cases:

(1) if there are more than 1 entry besides url, the entry name should use "note".

@misc{c.elmohamed,
author = "Saleh Elmohamed",
note = {\url{http://www.npac.syr.edu/projects/
cpsedu/summer98summary/ examples/hpf/hpf.html}}
}


(2) if there is only url entry, the entry name howpublished will work as well.

@misc{exam1,

howpublished = {\url{http://www.npac.syr.edu/projects/
cpsedu/summer98summary/ examples/hpf/hpf.html}}
}
