This might be vary basic but I still need a bit of help to figure this out. I have a relatively large cell array
data={411x7cell 411x7cell 411x7cell 411x7cell 411x7cell ' '}
with data{1,6} being empty. How do I remove/delete this cell from the array. I tried
data(strcmp(' ',data)) = [];
But without luck. Please help... THANKS

The question originally showed a 1x1 character, now you have a 1x1 cell array containing an empty string. Please actually be precise and define the exact specification of what you want. Changing the specifications does not make it easy to help you.

I want to delete the 1x1 cell array containing an empty string. Alternatively I can replace the '' with whatever I want like NaN, but the overall aim is to delete the empty string (or NaN string). I hope this help as I am very new to matlab coding.

@JB, Stephen's comment is spot on. It may not seem like a big deal to you but your language and your syntax is very imprecise and makes it difficult to answer the question approprietely. There is a big difference between:
data={411x7cell 411x7cell 411x7cell 411x7cell 411x7cell ' '}
and
test = { {'a', 'b', 'c'}, {'d', 'e', 'f'},{''}}
The former is a cell array where some cells may be empty (the others containing cell arrays). Removing those empty cells is trivial:
data(cellfun('isempty', data)) = [];
The latter is a cell array where no cell is ever empty, all cells being themselves cell arrays. Some of these subcell arrays may be empty. Removing these empty cell arrays within cell array is a bit more complicated, since you now need to dig through two cell arrays to test for emptyness:
test(cellfun(@(c) all(cellfun('isempty', c)), test) = [];

You may get some idea from below code
s={'dsfd ' ,'sdfsdf sdfsd sdfsd',' sdfsdfs'}
newStr = erase(s," ")%removes empty spaces
