fp31 ='#CC' '#CB' '#CN' '#CO' '#CP' '#CF' '#CS' '#CI' '#CQ' '#CW'
i have a cell array like this .. i want to convert every single cell of the array to string.
fp31(1)='#CC' should be string.

In R2016b or later, you can do
fp31 = string({'#CC','#CB','#CN','#CO','#CP','#CF','#CS','#CI','#CQ','#CW'});
and then fp31(1) would be the scalar string "#CC" as a string object. The corresponding character vector would be fp31{1}

If your cell array is this:
fp31={'#CC','#CB','#CN','#CO','#CP','#CF','#CS','#CI','#CQ','#CW'};
access the elements using brackets:
fp31{1}
ans =
#CC
which will be a string array

@Stephen (and Image Analyst) - everything you said is spot on, I was clueless I had nested cell arrays. I deleted my comment since like you said, it's not related at all. Sorry for being retarded.

Try this:
fp31={'#CC','#CB','#CN','#CO','#CP','#CF','#CS','#CI','#CQ','#CW'}
c = char(fp31) % Create 2D character array.
If some of the strings in fp31 are longer than others I think it pads with spaces so that the array is rectangular, as all matrices must be.
That's how to convert to "strings", but like David said every single cell contains a string and you can get to it without doing anything, so we don't know why you're asking what you asked. I think the FAQ will give you a good intuitive feel for how cell arrays work: http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F

Starting with r2017b, there is also a convertCharsToStrings() function that people may want to know about. From the help:
Convert a cell array of character vectors to a string array.
C = {'Venus','Earth','Mars'}
C = 1x3 cell
{'Venus'} {'Earth'} {'Mars'}
str = convertCharsToStrings(C)
str = 1x3 string
"Venus" "Earth" "Mars"
