Kronecker

Given 2 subscripts, j & k, KronD will return 1 if j == k and 0 if j != k.A very simple function with only a single if-else statement. Saves a bit of typing when the Kronecker Delta is needed. Platforms: Matlab

This file serves as a replacement for Matlab's kron.m. It contains a more efficient implementation of the Kronecker product for dense, sparse and logical matrices. Platforms: Matlab

The vectorized transpose matrix, Tmn, is the matrix that permutes the vectorization of an m#n matrix A into its transpose vectorization. For example, if the vectorization of A is defined as vec(A), or A(:), then Tmn*vec(A) = vec(A').EXAMPLEThe vectorized transpose matrix can be used to reverse... Platforms: Matlab

Superkron is a generalization of Matlab's kron function. It allows to compute the kronecker product of more than two matrices in one shot, and also works for multidimensional arrays having more than two dimensions. Platforms: Matlab

The package contains a set of C functions and preprocessor macros to simplify writing MEX source files. The routines help check input and output argument count, argument type, dimension and structure in a MEX file. See "common.c" in the subfolder "include" for details.Sample code is included in...
