Julia 中多个条件的三元运算符

Question

我有如图所示的 Julia 代码

if cxp1_v1 < cxp1_v2 
    d_min = cxp1_v1 
    d_max = cxp1_v2 
else 
    d_min = cxp1_v2
    d_max = cxp1_v1 
end

或

if cxp1_v1 < cxp1_v2 d_min, d_max = cxp1_v1, cxp1_v2 else d_min,  d_max  = cxp1_v2, cxp1_v1 end

有没有办法在三元运算符中完成同样的事情？我尝试了如图所示的东西

cxp1_v1 < cxp1_v2 ? d_min, d_max = cxp1_v1, cxp1_v2:d_min,  d_max  = cxp1_v2, cxp1_v1

但我明白了

syntax: colon expected in "?" expression

Stacktrace:

Answer 1

cxp1_v1 < cxp1_v2 ? (d_min, d_max) = (cxp1_v1, cxp1_v2) : (d_min, d_max) = (cxp1_v2, cxp1_v1)

但我可能会写成：

d_min, d_max = cxp1_v1 < cxp1_v2 ? (cxp1_v1, cxp1_v2) : (cxp1_v2, cxp1_v1)

因为看起来更容易阅读，甚至：

d_min, d_max = minmax(cxp1_v1, cxp1_v2)
