Images and Matrices: Using SPY This demo had a very neat graphic which caught my attention. Reading the description, I stumbled upon the term "sparse matrix". After some Googling, I discovered that sparse matrices are matrices with a high proportion of zero entries. Sparse matrices are useful because they can be compressed. When considering digital images, compressed sparse matrices reduce the amount of space needed to store and transport an image. Also, these matrices can be manipulated to create cool images (see link-- Sparse Matrix Graphic). Can't wait to learn enough MATLAB and make something that awesome.
