searching for strings in array of character/strings matlab

Question

I have the following array:-

dir=['E','B','R']

I want to find the index of the elemen 'E'.

>> find(dir=='E')

ans =

     1

But i want to do the same for an array of strings rather than array of characters like:

dir=['E','G','T','BR']

But there is an error to find 'BR'. I want the output to be 4.

>> find(dir=='BR')
Error using  == 
Matrix dimensions must agree.

How to work-around this error?

I recommend you look at the documentation on string (char array) handling in matlab such as here.

What you want to do is work with cell arrays of strings:

 dir = {'E','G','T','BR'}
 find(ismember(dir,'BR'))

 ans = 4
