matrix

• Interconnection of programming function is carried out on a matrix board .
  各种编程功能之间相互衔接在矩阵板上进行。
• If a is the mxn matrix, then the nxm matrix is called the transpose of a .
  如果A是mxn矩阵，那么nxm矩阵为A的转置矩阵。
• It is convenient to shift from index to matrix notation at this point .
  为了方便起见，这里我们把下标记法改为矩阵记法。
• a complex n×n matrix u is called unitary if u*u=in.
  一个复nn矩阵U如果U*UIn，则称它为酉矩阵。
• Local deviations depend strongly on the local geometry of the solid matrix .
  局部偏离严格地依赖于固体矩阵的局部几何形状。
• This can be extended to nxn tridiagonal matrix with l, u bidiagonal .
  把它推广到nxn三对角线矩阵使具有两对角线的矩阵L、U。
• next, define the constant elements hij of the n×n hessian matrix h.
  其次，定义nn海赛矩阵H的常数元数为hij。
• In other words, the hermiticity of a matrix is invariant under unitary transformations .
  换言之，矩阵的厄密性在幺正变换下保持不变。
• This would certainly militate against good bonding between the resin matrix and the glass .
  这当然会影响树脂基体与玻璃间的良好粘结。
• Since i behaves like the number 1 in ordinary algebra it is called the identity matrix .
  由于工具有普通代数中数1的性质，称它为幺矩阵。
