Problem with find string in array
显示 更早的评论
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.

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

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