Finding Patterns in Array

Hi guys, how do I find in my specific binary pattern in another array that has binary values? I mean lets assume I have

a=[1 0 1] (binary values)

the other array b=[1 1 1 1 1 1 1 1 0 0 0 0 0 1 1 1 1 0 1] (binary values)

So Im searching inside b about a which I want to return the started index of my pattern in other other array, any help how could I implement that?

Look into strfind.

idx = strfind(b,a); % strfind implicitly converts a and b to char arrays

Hi !

but my purpose is to find the started index of my pattern in the other array!, not actually converting to string ..

strfind does the job.

Your vectors a, and b remain unchanged. The output of strfind is a start index for each occurence of a in b as you requested.
