Index a Matrix that gets smaller

I have a cell array that I am deleting any rows with empty values, and while indexing I run into the error:

"Index in position 1 exceeds array bounds (must not exceed 347)."

Here is the script for the part that has the issue, how can I index a cell array while deleting stuff as it goes?

for ind=2:size(RAW)
    if sum(strcmp('',RAW(ind,4:7)))~=0
        RAW(ind,:)=[]
    end
end

note: I am skipping the first row intentionally, and also only checking columns 4 through 7

for ind = size(RAW): -1 : 2

Replacing the for statement with that worked perfectly, thanks.
