Hello, i try to find mark 'bmw' in Mfg table(carbig.mat).I want to create new logic table with 1 (if string exist) or 0 to others string.
>> idx = ismember((Mfg(:,1:6)=='bmw'),[1,1,1,1,1,1],'rows')
But i have this mistake:
Error using ==
Matrix dimensions must agree.
It's my workspace:

First convert the character matrix to a cell array of strings or to a string array without leading/trailing space characters and then use strcmpi.

Would you attach a sample file ?
@madhan, if you type
load carbig.mat
you'll have the data. It is a file used for examples in the documentation.

Undefined function 'contains' for input arguments of type 'cell'.

Do you have an older version of MATLAB? The contains function was introduced in R2016b.

Yes, i have 2015b
This is more awkward, but will work
not(cellfun(@isempty,strfind(cellstr(Mfg),'bmw')))
I expect there is something more elegant.
