Undefined function 'contains' for input arguments of type 'char'

Hi,

I am trying to use contains to check if string A has string B in it. Say, A = 'XYZXYZ', B = 'XY', I am using: tf = contains(A, B); But I keep getting error "Undefined function 'contains' for input arguments of type 'char'" Why?

Thanks in advance for any help. Jennifer

Are you using an older version of MATLAB? According to the documentation for contains, this function was introduced in version R2016b.

You might be able to use strfind instead.

Oh, I am using 2015b. OK. I will use strfind instead. Thanks.
