Hi there I have been using strfind to find strings within a string.
Now lets imagine a horizontal axis of time. I want to do strfind of two strings in one go. So lets say we have two strings consisting of 1's and -1's and 0's......then i want to do strfind of 101 of both strings and find the same location.....I hope somebody understands this.

What's wrong if you just do them separately and then see if there is an intersection?
x1 = num2str(rand(1,10)>0.5)
xloc1 = strfind(x1,num2str([1 0 1]))
x2 = num2str(rand(1,10)>0.5)
xloc2 = strfind(x2,num2str([1 0 1]))
intersect(xloc1,xloc2)
