Help needed : searching for a sequence in an array

[austinpowers]

how to search for some sequence in an single dimension array,

suppose i have an array with elements
[4 3 1 6 2 5]

and i want to search whether element 1 comes before 2 or not

so i want to search for sequence 1 2

Your last two statements are inconsistent. if 1 comes before 2, that's not the same as looking for the sequence 1 2.

thanks for replying ttfn


what i meant there by saying sequence is

like 1 should come before 2 ,

it doesnt matter whether there is any other element between them or not,

if i was given two elements from that sequence
[4 3 1 6 2 5]
, i should say which element comes before using matlab.

How about something really simple using find:


x=[4 3 1 6 2 5];

firstval=x(min(find(x==1),find(x==2)))
