[Scilab-users] Search for a subvector in a vector

[Dang Ngoc Chan, Christophe]

Hello,

I probably missed something obvious but here is my trouble :
I have a vector a = 1:6
and want to locate b = [2 3 4] inside a (the result being 2).

So I know members() which locate any of the elements of b inside a
and vectorfind() which can search a vector inside a matrix.

I searched the archive of the list and found topics about Matlab ismember()
and locating a phrase in a text.

But none of these are convenient.

As my vector is rather small, I can do

aa = [a(1:$-2)  ;  a(2:$-1) ; a-3:$)]

vectorfind(aa, b, "c")

but I wonder if there is a better (vectorised) solution?

Regards
