I have an undergraduate working with me on some simulations, and I've been teaching him Matlab for the last year. This week I showed him a useful trick for changing the look of some line plots. He has a whole bunch of these to do, and instead of

The Problem Some of the figures I create can be presented on either logarithmic or linear scales. After creating a plot, I may want to switch scales, but I don't want to type set(gca, 'XScale', 'log') every time (nor do I want to

The Problem Usually I like to see MATLAB figures as they are produced, but if I'm running a long script, visible figures can clutter the screen and hog the available memory. I wanted a way to change visibility quickly, easily, and without having to remember how I did

Problem MATLAB *.fig files won't open. Key Symptoms * when double-clicking on a *.fig file in a folder, no figure is shown in MATLAB; e.g. on a Mac, after double-clicking the file, you see the opening animation, but no signs in MATLAB that the file actually opened * no
