using strcmp for index

I have a data file that must be in a specific order through a descending column. I want to check that the data in my cells is in the correct order.

my file should have the following order within the 4th column:

'BLCU'
'BLCD'
'BLCU'
'BLCD'
'BLCU'
%etc etc. also, I have another file that has the following order in (again, the 4th column)%
'OGCU'
'OGSS'
'OGES'
'OGSA'
'OGLO'
'OGCD'
%trials is the name of my array
%was thinking of something along the lines of underneath (this obviously does not work)
for x = 1:100
    strcmp(trials{x:x+1,4},'BLCU' 'BLCD')
    disp(trials{x,3})
end
%ie making sure that each "chunk" of code is in the correct order before proceeding to the following chunk

My chunks have to be in the correct order and they have to follow one another, but obviously strcmp() cannot compare two cells at once. I would like to return the index (located in cell 3) where the error occurs if a chunk is incorrect. Finally, I also need to detect typos (ie. a OGES labeled as a OGED, etc).

Thanks in advance

Try this:

pos{x} = strcmp(trials{x},{'BLCU' 'BLCD'});
