Module compute::utils

Functions

design	Create a design matrix from a given matrix.
dot	Calculates the dot product of two equal-length vectors.
invert_matrix	Given an n by n matrix, invert it. The resulting matrix is returned as a flattened array.
matmul	Multiply two matrices together, optionally transposing one or both of them.
toeplitz_even_square	Given a vector of length n, creates n stacked duplicates, resulting in a square Toeplitz matrix. This function also assumes evenness. That is, x_i = x_{-i}.
xtx	Given a matrix X with k rows, return X transpose times X, which is a symmetric matrix.
