off-diagonal elementsとは 意味・読み方・使い方

A coefficient matrix A is incompletely triangular-factorized into a lower triangular matrix L and an upper triangular matrix U, and diagonal elements and off-diagonal elements of L and U are multiplied by respective scaling parameters to form a lower triangular matrix L' and an upper triangular matrix U'.例文帳に追加

係数行列Ａを不完全三角分解して下三角行列Ｌ、及び上三角行列Ｕを得た後に、Ｌ及びＵの対角要素と非対角要素のそれぞれにスケーリングパラメタを乗じ、下三角行列Ｌ′及び上三角行列Ｕ′を得る。 - 特許庁

The load circuit Z of the inverter circuit INV includes an LC resonance circuit and a period in which the load circuit Z is isolated from a filter capacitor C0 as a direct- current power supply is provided by turning off one of the switching elements in the diagonal positions in a period for which a resonance current flows.例文帳に追加

インバータ回路ＩＮＶの負荷回路ＺはＬＣ共振回路を含み、共振電流が流れる期間に対角位置の一方のスイッチング素子をオフにすることで、負荷回路Ｚを直流電源である平滑コンデンサＣ０から切り離す期間を設ける。 - 特許庁
