Matrix Reloaded Cast

This brand new 3D screensaver will give you a chance to get an inside look at the way the Matrix works. You will find yourself in the long white corridor with multiple doors on either side all looking exactly the same. Behind these doors are various realizations of the Matrix. Some look very...

Function: * Matrix inverse. * Matrix transpose. * Largest component. * Smallest component. * Matrix or vector norm. * Dimension. * Sum of diagonal elements. * Determinant. * Matrix rank. * Eigenvalues. * QR factorization. Orthogonal-triangular decomposition. * LU factorization. *...

This SMAWK algorithm takes as input a function for computing matrix values, and searches for the position of maximum value in each row. The matrix must satisfy the "totally monotone" property: in each submatrix (in particular each 2x2 submatrix) the positions of the maxima must move leftward as...

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 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...
