Emacs short-cut




M-x
org-emphasize
org-mode
 

You can make words *bold*, /italic/, _underlined_, =verbatim= and ~code~, and, if you must, ‘+strike-through+’. Text in the code and verbatim string is not processed for Org mode specific syntax, it is exported verbatim.

pdfcrop with margins



http://askubuntu.com/questions/124692/command-line-tool-to-crop-pdf-files

If you wish to crop a pdf with left, top, right and bottom margins of 5, 10, 20, and 30 pt (points), then run
pdfcrop --margins '5 10 20 30' input.pdf output.pdf
in terminal. To actually crop something away, use negative values in the argument for crop. For example,
pdfcrop --margins '-50 -50 -50 -50' input.pdf output.pdf
crops 50 pts from the left, top, right, bottom (in this order).
If you run only the command pdfcrop input, it will output a file titled input-crop.pdf with zero margins. I find this very handy when including pdf illustrations in documents.
Cropping multiple files
Unfortunately, pdfcrop cannot crop multiple files at the time. It is however easy to write a script that will crop all pdfs in the folder the script is located in.
Create a new empty file, and call it something.sh. Open it with a text editor and insert the following:
#!/bin/bash

for FILE in ./*.pdf; do
  pdfcrop "${FILE}"
done
Save it, and close. Then right click the file, go to Properties > Permissions and check the field Allow executing file as program. Now close the dialog. Run the script by double clicking it and choosingRun in Terminal. And new, zero-margin cropped version of all pdfs with suffix -crop will now be printed in the folder. If you want margins or other things, you can of course just open the script and add arguments after pdfcrop.

% LinearRegression example
% x=0:1:9;

% [p,Rsq] = LinearRegression (x,y) ;
% yfit = p(1)*x + p(2) ;
% plot(x,y,"o",x,yfit) ;
p = polyfit(Xin,Yin,1);
Yfit =  p(1) * Xin + p(2);
Yresid = Yin - Yfit;
SSresid = sum(Yresid.^2);
SStotal = (length(Yin)-1) * var(Yin);
Rsq = 1 - SSresid/SStotal;
