FAST MATRIX MULTIPLICATION AND LINEAR ALGEBRA BY ALTERNATIVE BASIS

摘要

A computerized method comprising operating one or more hardware processor for receiving a first matrix and a second matrix. The hardware processor(s) are operated for determining a basis transformation, wherein the basis transformation is invertible to an inverted basis transformation. The hardware processor(s) are operated for computing an alternative basis first matrix by multiplying the first matrix by the basis transformation. The hardware processor(s) are operated for computing an alternative basis second matrix by multiplying the second matrix by the basis transformation. The hardware processor(s) are operated for performing a matrix multiplication of the alternative basis first matrix and the alternative basis second matrix, thereby producing an alternative basis multiplied matrix. The hardware processor(s) are operated for computing a multiplied matrix by multiplying the alternative basis multiplied matrix by the inverted basis transformation.
