Matlab, Beer(RGB)=BlueMing(BGR)

I was playing around learning Matlab and the suggested .jpg was of a apple… this seems much better. In this I have just swapped the RGB values of the image to give false colour shuffles of the file. Yes… I could have done this in Photoshop… but this is more impressive I think! What is worrying is BlueMing is beer with the colours reversed!


Learning Matlab

I can’t wait for my new computer! At the moment I’m trying to learn enough Matlab for multi-variate analysis of SIFT and E-Nose data on a reduced version of Matlab on my laptop! The version of Matlab has no toolbox’s (handy when PCA and stats toolbox’s are referred to in the literature) and as my laptop only has 256Mb of RAM (Matlab requires a minimum of 512, and prefers a gig!) so my laptop is prone to crashing every time I try something new!
I have managed to make basic bar graphs of some of the data I have been given and am beginning to see the benefits of all variables as matrices but I’m not too keen on the fancy environment that Matlab provides.
