Matrix Decomposition

X must be a N-by-K matrix, N is the number of "candidate" and the K is the number of "judge".

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...

A colour (RGB or 3-channel) image may be converted to a quaternion matrix by placing the three colour components into the three quaternionic imaginary parts, leaving the real part zero. The quaternionic singular value decomposition is a technique to decompose the quaternion matrix (representation...
