Matrix Math

This script defines the Matrix class, an implementation of a linear algebra matrix. Arithmetic operations, trace, determinant, and minors are defined for it. This is a lightweight alternative to a numerical Python package for people who need to do basic linear algebra. Vectors are implemented as...

This script presents you three ways to calculate a distance matrix out of a list of n-dimensional points using scipy.

The library supports only basic matrix operations, not being suitable for large matrices.It has been tested with:Borland C++ 5.0 (both 16 and 32 bit);Borland C++ 5.5;C++ Builder version 1.0, 3.0, 4.0 and 5.0;MS Visual C++ version 4.0, 4.2, 5.0 and 6.0;SUN g++ under Sun Solaris;GNU C++ and SGI C++...

This function gives the decimation matrix which after post mulitpling it with the given signal gives the downsampled version of the original signal...D = decimmtx(x,N)decimates the given signal by a factor of N.[D,y] = decimmtx(x,N)gives D as well as the decimated signal y

CONV_MTX Convolution matrix. If 'x' is a column vector of length 'nx', then conv_mtx(x,nh) gives a toeplitz matrix 'X' of size (nx+nh-1) times (nh). 'nh' is the length of the column vector 'h' with which 'x' is convolved. Thus finally 'X*h' is same as conv(x,h). If 'x' and 'h' are row vectors,...

write_matrix_bin(f,m) saves the matrix "m" in a binaryfile "f". write_matrix_bin is a lot faster than the built in function save(), andtakes up much less diskspace than the old "save -v6" which doesn't use compression.write_matrix_bin also includes an option for compression with...

sometimes, you want an image that contains text, instead of manually drawing 1s and 0s , this functino takes a string and returns a matrix of 1s and 0s in the form of that string. (tjhe matrix is rectangular the text string is represented as being painted by 1s)

This is a learning model for matrix-based data. It can be more efficient than standard vector-based models when the training sample is small or the inputs are matrices, since this model has less parameters than standard ones and exploits an inner structure of the inputs. This model can be...
