Hi,

I have below cell array, and want to get row indices of names ends with "_A". I am working in Matlab2016a.

Names:

{'HATY_A';'VANU_BA';'IKLA_A';'PAIK_A';'HANYT_BH';'HAYIO_HNA';'HAKIO_A'}

desired_output:

rowIdx=
1
3
4
7

I use below code: pattern='_A'

rowIdx=endsWith(Names,pattern) 
also tried 
rowIdx=contains(Names,pattern)
but both doesn't work in 2016a. Kindly someone help how to get my desired output.

For older versions:

>> Names = {'HATY_A';'VANU_BA';'IKLA_A';'PAIK_A';'HANYT_BH';'HAYIO_HNA';'HAKIO_A'};
>> find(~cellfun('isempty',regexp(Names,'_A$','once')))
ans =
   1
