【答案】应助回帖
你好，下面是计算的过程。我用matlab写的程序计算了一下：
首先，轴角对转化为G矩阵：
G_matrix = index2G([59.7,0.589,0.578,0.565])
G_matrix =
0.6763 -0.6563 -0.3341
-0.3191 -0.6699 0.6702
0.6638 0.3467 0.6626
G_matrix2 = index2G([60,1,1,1])
G_matrix2 =
0.3333 -0.2480 -0.1220
-0.1220 -0.1667 0.4553
0.4553 0.1369 0.3333
计算两个取向矩阵的取向差矩阵：
mis_G = G_matrix2*(G_matrix')
mis_G =
0.4290 -0.0220 0.0545
-0.1253 0.4558 0.1629
0.1067 -0.0136 0.5706
计算所有的取向差角：
sdaxis=DA_MIS_C(mis_G)
sdaxis =
0.9629 0.0865 -0.0007 0.9962
90.0033 -0.0076 -0.0001 0.0076

完成。
我现在不确定，是否一定要计算所有等价取向了，sigh！ |
