Grasa Corporal, omron, plicometro

La verdad es que esto de medir la grasa es todo un Expediente X..

Con cada uno es un mundo, y si te la mides hoy, no te da lo mismo que mañana...

Yo opte por utilizar un metodo que me dijo alguien en el gimnasio..

"...Tu mirate al espejo y si te ves de puta madre, tienes mejor estado fisico.. corres 4 kilometros o los que sean, estas bien contigo... que mierda importa la grasa?¿.."

Daniel.

$g++ `pkg-config --cflags --libs opencv` anycode.cpp -o anycode

Package opencv was not found in the pkg-config search path.                                             
Perhaps you should add the directory containing `opencv.pc'

No package 'opencv' found

Solution
1) find opencv.pc
$ locate opencv.pc

/mnt/vol3/installers/opencv/opencv-2.4.8/build/unix-install/opencv.pc      
...    
/usr/local/lib/pkgconfig/opencv.pc  

2) then add to enviroment variable the path
$ export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig/

Latex recursos

Cuando queremos colocar varias imágenes en una misma fila [4] y [5], nos dan un ejemplo para colocar 3 imágenes en una, cada una usa comandos diferentes.

\begin{figure} 
  \begin{subfigure} [b]{0.3\textwidth}
     \includegraphics{}
  \end{subfigure}
  ...
\end{figure}

\begin{figure}
  \minipage{0.32\textwidth}
    \includegraphics{}
  \endminipage
  ...
\end{subfigure}

Cuando las imágenes se desordenan es decir no conservan el lugar que queremos podemos usar [6], que resumido seria:

\begin{figure}[htpb]
  ...
\end{figure}
