Since your variable is a cell array, the expansion from the colon
subscript returns a comma-separated list, not a single array. Since
it's text and not same length, [] aren't sufficient to catenate the
elements, hence CHAR() to do that job.

Alternatively,

 >> idx=find(~cellfun(@isempty,strfind(SGandCP(:,1),'Steel')))
idx =
      7

Cell arrays are handy for disparate data types, but a
pit(proverbial)a(ppendage) to work with...

I'd suggest there would be good spot for a table that would make lookups
much simpler.
