Eigen face to plot with image?
Hello all, I have followed the eigenface logici into my images. In order to see the eigenfaces as images, I have used "imagesc". Here is the code I referred. http://www.cs.ait.ac.th/~mdailey/matlab/#refs My question is this. It is simple to display an eigenface as an image, using the built in imagesc fun... 6 Jan 2010 08:46

Hi, Apologies in advance if my question is a bit convoluted and long winded but this is my first post and I wouldn't profess to be a Matlab expert . . . I'm currently working on a ZigBee simulation of the physical layer for a university project. Please no replies saying "do your own work" because as you'll see... 6 Jan 2010 08:44

Large matrix handling
Hi, I need to deal with a very large matrix in Matlab, i.e. image(21600, 43200). With a floating point type, this matrix will take more than 3 GB memory. With a 64-bit machine and OS, this amount of memory can be allocated. But Matlab seems not be able to allocate that much of memory automatically. Does anybody ha... 6 Jan 2010 08:47
