1 次查看(过去 30 天)
I = find(X == a,1,'first'), J = find(X == b,1,'first'), K = find(X == c,1,'first') provided that K > J > I How can I implement the conditional part? Thanks in advance.

X = [10 20 30 40 50 10 20 30 40 50];
a = 30;
b = 20;
I = find(X == a, 1, 'first')
I = 3
J = find(X((I+1):end) == b, 1, 'first') + I % start search after index I
J = 7
X(I)
ans = 30
X(J)
ans = 20

Is it possible to write your codes in terms of > or < ?

Sure, just change the == to whatever you want instead.
