出于好奇,我正在研究一个研究问题,我不知道如何编程我想到的逻辑.让我向你解释一下:
我有四个载体,例如,
v1 = 1 1 1 1
v2 = 2 2 2 2
v3 = 3 3 3 3
v4 = 4 4 4 4
现在我想做的是将它们组合添加,即
v12 = v1+v2
v13 = v1+v3
v14 = v1+v4
v23 = v2+v3
v24 = v2+v4
v34 = v3+v4
直到这一步它很好.问题是现在我想要从v1,v2,v3,v4中添加这些向量中的每一个,它之前没有添加过.例如:
v3和v4尚未添加到v12,因此我想创建v123和v124.类似地,对于所有的矢量,
v12 should become:
v123 = v12+v3
v124 = v12+v4
v13 should become:
v132 // This should not occur because I already have v123
v134
v14 should become:
v142 // Cannot occur because I've …
