scalar matrix

基本解釋

At very low frequencies, the contribution from the vector potential to the impedance matrix is much smaller than the contribution from the scalar potential.
當頻率很低時，阻抗矩陣中矢量磁位的貢獻比標量電位的貢獻小得多。
The idea of complex formal derivatives is generalized from scalar to vector and matrix at first, then the manipulation rules of complex formal derivatives are derived systematically.
將原來僅限于標量的復(fù)形式導(dǎo)數(shù)，推廣到復(fù)向量和復(fù)矩陣的范圍，并系統(tǒng)地導(dǎo)出了復(fù)向量和復(fù)矩陣形式導(dǎo)數(shù)的運算法則；
