如何在matlab中找到数组另一行的对应点？

Question

i have an array lets say 我有一个数组可以说

x = x =

 1     2     2
 5     8     7

now i want to get the corresponding values of a number in 2nd row. 现在我想在第二行中获取数字的相应值。 like i have number =2 就像我有数字= 2

and i want 而且我要

ans= 8 and 7 ans = 8和7

as 8 and 7 are the corresponding points for 2. 因为8和7是2的对应点。

Answer 1

X(2,X(1,:)==2)

should do. 应该做。 Hope you can figure out how. 希望你能弄清楚。
