subaxis

subaxis allows you to adjust the spacing in a subplot. Use subaxis instead of subplot.

% To fill the first column of a 4 by 3 plot:

h = subaxis(4,3,(i*3-2), 'Spacing', 0.045);

rounded buttons

Say you want some rounded buttons on a webpage, and you make your buttons in Powerpoint because you don't know what else to do. You may run in to problems for cropping those rounded buttons because most crop programs make only exact rectangles.

Here is a solution:

1. Make the buttons in Powerpoint (or Illustrator)
2. If you made them in powerpoint, screenshot a high resolution version (I did this from opening a PDF saved from the Powerpoint in Illustrator.)
3. Open screenshot in Photoshop. (mine was a .png)
4. Press "C" to open the crop tool and crop close in to the button, then press "return" to crop.
5. If your button is outlined, press "W" for the wand tool and click to outline the surrounding area outside the button.
6. With the outside area highlighted, press "delete"
7. Save for a web device, GIF, transparency "background color" (this will make the area around the button transparent so you can have rounded buttons)

Here's an example of the result:

remove unwanted link underlining

Some website templates will automatically underline any links you have, even image links, which is a little unsightly.

You can get rid of it by surrounding the image with a div style tag:

<div style="text-decoration: none;"> </div>

And to display greater than or less than signs in html (like above) you can use < and >
