the attached utility is a work I ve submitted to the university It shows what a jpeg compression is all about. the function implements the DCT transform, using a matrix operator. note that matlab has a function for the DCT and iDCT transforms that might be more efficient.(the attached utility is a work I ve submitted to the universityIt shows what a jpeg compression is all about.the function implements the DCT transform, using a matrix operator.note that matlab has a function for the DCT and iDCT transforms that might be more efficient .)

matching pursuit 算法，matlab实现，信号稀疏分解方式的一种，适合与信号在超完备的原子库中稀疏分解。matchingpursuit.m(A matching pursuit algorithm. It fits data from a set of dictionary elements by orthogonally projecting the data onto elements of the dictionary of vectors such that the energy in each projection is maximized. In constrast to G-S, the residual is orthogonalized, not the basis vectors)

For inverting a matrix, Gauss-Jordan elimination is about as efficient as any other method. For solving sets of linear equations, Gauss-Jordan elimination produces both the solution of the equations for one or more right-hand side vectors b, and also the matrix inverse A(-1). However, its principal weaknesses are (i) that it requires all the right-hand sides to be stored and manipulated at the same time, and (ii) that when the inverse matrix is not desired, Gauss-Jordan is three times slower than the best alternative technique for solving a single linear set.
