figures in latex

Q: I want to put a figure into a latex document. I am trying things, but the image is not appearing when I compile it.

A: You need to use:
 \usepackage[pdftex]{graphicx} instead of
\usepackage[dvips]{graphicx}.

histc, histogram count

http://www.mathworks.com/help/techdoc/ref/histc.html

n = histc(x,edges) counts the number of values in vector x that fall between the elements in the edges vector (which must contain monotonically nondecreasing values). n is a length(edges) vector containing these counts

Very useful. Plot histogram points instead of bar graph. Need to calculate bin centers and use as x values. Divide the result of histc by the length(x) to get the y values. Plot.

illustrator shortcuts

After decades of using Illustrator in a dumb way (okay maybe only 1.4 decades), I learned a few key points.

  • If tracing an original, make it a layer, name it, and lock it.
  • Make a new layer, name it, and draw on it. 
  • Use shortcut Z, zoom
  • Use shortcut V, arrow
  • Use shortcut [space], hand
  • Use the different "corner" options (near the stroke box) so they're not pointy or pointy.
I think that's all.

vectorizing an image

Vector Magic

http://vectormagic.com/home

Takes an image that may become pixelated upon enlargement and vectorizes it into .pdf or other format. I used it for a logo that we wanted to blow up for a banner. Pretty neat. Two free conversions.

artboard size in Illustrator

Adobe Illustrator is yet another program that I have never fully grasped. 

But here's how to change the size of the "Artboard" (corresponding to the "page", and holding the artwork that is printed or saved as PDF).

File > Document Setup > Edit Artboards

You should get a drag-able box. 

Useful if you want to scale a 6-inch image by 1000% for a banner.

tables are out, DL, DT, DD is in

Some info on using definition lists to make table-like displays that are more maintainable:

You can add the style information to the .css or to the top of the html page to test e.g.

style type="text/css"
dl dd { padding-bottom:0.5em; }
dl dt {float:left;} dt {text-align:left; width:8em;}
dl dd {margin-left:9em;}
dl { padding-bottom:0.5em; }

(add style tags before and after)
