You can download the M_Map toolbox either as a gzipped tar-file ,or as zip archive(Click on these links to download - note, some problems with this have been reported by users of the Chromeweb browser). If you are unpacking the zipfile MAKE SURE YOUALSO UNPACK SUBDIRECTORIES! Both are around 650k in size. Once you havethisarchive, read the Getting started sectionof the User's guide to correctlyinstall this toolbox, and sections 8.6and 9.3 to install ETOPO1and GSHHS respectively.A number of examples are available tohighlight the various capabilities of M_Map (thumbnails are shownabove).
Gabor patches are sinusoidal gratings, typically with a Gaussian envelope, which are frequently used as stimuli in psychological experiments. Using this page you can easily create and download high quality Gabor patches.As with most topics, you can find out more about Gabor patches on Wikipedia.
In general Python has the advantage of being free, open source, and more versatile. Their NumPy and SciPy packages have similar functions to MATLAB. Python is a pretty elegant and intuitive programming language compared to MATLAB. It was created to be a generic language that is easy to read; and they definitely succeeded with that! Python is universally accepted as the better alternative to MATLAB for other programming needs besides data analysis.
The big disadvantage of MATLAB is that it's not free, a commercial license will run you $2,150. They also charge more, typically $1,000, for additional toolboxes; and I'd recommend the signal processing toolbox for vibration analysis. Don't worry though, I didn't use any functions in that toolbox for this analysis or the ones covered in my vibration analysis basics blog. Here's a full price list of the MATLAB products. MathWorks (the makes of MATLAB) are smart with their pricing though in that they offer significantly discounted licenses to students (get the entire suite including all toolboxes for $99) and to home users ($149 for MATLAB, $45 for signal processing toolbox). So must engineering students will come out of university with a knowledge and preference for MATLAB. They then take this preference to their future employer giving MATLAB the edge. 2b1af7f3a8
