This package can manipulate matrices with Lapack and OpenBlas libraries.
It uses the PHP FFI extension to call the Lapack and OpenBlas and perform several types of operations with matrices. Currently, it can :
- Matrices decomposition (LU, SVD, Eigen, Cholesky)
- Matrices Signal-processing (1D, 2D Convolution)
- Poisson,Gaussian Matrices
- Calculate the product of a general matrix and another general matrix
- Calculate the product of a symmetric matrix and a general matrix
- Update rank n of a symmetric matrix
- Update rank 2k of a symmetric matrix
- Compute the product of a general matrix and a vector stored in a band format.
- Compute the product of a column vector and a row vector. (Real number)
- Calculates the index of the element with the largest absolute value in the vector.
- Calculates the index of the element with the smallest absolute value in the vector.
- Exchange the contents of the vector.
- Compute the Euclidean norm of a vector.
- Add vectors
- Calculates the sum of the absolute values of each component of the vector.
- Rotate about a given point.
- Given the point P (a, b), rotate this point to givens and calculate the parameters a, b, c, and s to make the y coordinate zero.
- Multiply a vector by a scalar.
- Etc. |
