Image inversion in matlab

The following Matlab project contains the source code and Matlab examples used for image inversion. InvertIm generalized image inversion (grayscale reversal) This function has several options that are useful for inversion of medical images for use in other software.

Matrix approach to discretization of odes and pdes of arbitrary real order in matlab

The following Matlab project contains the source code and Matlab examples used for matrix approach to discretization of odes and pdes of arbitrary real order. This submission contains the basic functions that are necessary for using the matrix approach to discretization of fractional differential equations, and demos.

Growing a compiler in matlab

The following Matlab project contains the source code and Matlab examples used for growing a compiler. The tiny compiler is a kind of grammar. More capable compilers can be built, and so on. The components, and a paper describing them are included. This is a later version of FX 23255.
