MATLAB: Index a series of integers in a column of matrix

Question

I am trying to find a function that will produce what row a series of numbers are together. For example in a column of the following:

T2 = [2 7 4 5 1 0 1 3 1 5 6 7 4 7 2 7]'

I would like to find which row there is a specific transition between 2 and 7 and vice versa. I have used the find(T2 == 2 & 7) function, however, that produces the location of every single location where the integer is exactly equal to 2 and 7.

Any suggestions?? Thank you!

Answer 1

I am not sure what you want.

Try this:

T2 = [2 7 4 5 1 0 1 3 1 5 6 7 4 7 2 7]';
Idx = strfind(T2', [2 7])
Out = T2([Idx(:) Idx(:)+1])

producing:

Idx =
     1    15
Out =
     2     7
     2     7
