LU decomposition
Technical term in linear algebra; factorization of a matrix into a lower triangular and an upper triangular matrix.
To solve the system of linear equations, we computed the LU decomposition of the matrix.
Standard technical spelling using fullwidth Latin letters and kanji.
Halfwidth Latin variant commonly seen in technical documents.
From English 'LU decomposition', where L stands for lower triangular and U for upper triangular. The Japanese term is a direct borrowing with 分解 (decomposition).
