We present a general method for constructing orthogonal arrays related to this class of projection matrices in various cases , which makes the constructed arrays have higher saturated percents ) _ q ,本文提出了在各種情況下與這類(lèi)投影矩陣相關(guān)的正交表的構(gòu)造方法。
Mixed - level orthogonal arrays have additional appeal and receive more and more attention because they have great flexibility , allowing for factors with different numbers of levels 混合正交表的魅力在于它有較大的靈活性,允許試驗(yàn)因素具有不同水平數(shù),因此得到了越來(lái)越多的關(guān)注。
The main results are listed in the following : method for constructing orthogonal arrays by orthogonal decomposition of projection matrices and matrix images of smaller orthogonal arrays are further investigated 具體內(nèi)容如下: ?進(jìn)一步研究了由投影矩陣的正交分解構(gòu)造正交表的方法以及小正交表的矩陣象。
Moreover , the generalized hadamard product of two columns of an orthogonal array is extended to that of two orthogonal arrays , which makes the constructed arrays have more non - prime power level columns 推廣正交表兩列的廣義hadamard積到正交表的廣義hadamard積,使得所構(gòu)造的混合水平正交表具有較多的非素?cái)?shù)冪水平列。
Some new methods of construction of orthogonal arrays especially mixed - level orthogonal arrays are presented . these methods produce many new orthogonal arrays which are laid out by mean of a software matlab 給出了正交表特別是混合正交表的一些新的構(gòu)造方法,應(yīng)用這些方法獲得了一些新的混合正交表,并且用matlab列出了它們的具體形式。
