I have a cell array which looks something like this;
'DS 5376'
'FR 8241'
'B 1257'
'BG 09857'
'TR 3017'
I want to remove the central white space (or any white space to that matter) to get the following
'DS5376'
'FR8241'
'B1257'
'BG09857'
'TR3017'
Previous questions and suggested and I have tried using
cell_Array=strrep(cell_Array,' ','')
but to no avail - any ideas as to how I can acheive this?
Many thanks

If your example with strrep does not succeed, that would be because the whitespace is actually not a space. You can check what it is for sure by getting its ASCII value with:
double(cell_Array{1}(3))
If it is some other sort of whitespace (maybe a tab), you can use:
cell_Array = regexprep(cell_Array, '\s', '') %\s means any of \t, \f, \n, \r or \v
But if it is not, assuming your text is only letters, numbers or underscore, you can remove anything else with:
cell_Array = regexprep(cell_Array, '\W', '')

What? None of the regexprep succeeded?
Can you show the output of
double(cell_Array{1}) %i.e. the ASCII values of the whole string
The proper syntax for the cellfun would be:
flight_no = cellfun(@(s) strrep(s, ' ', ''), flight_no, 'UniformOutput', false);
But strrep operates on cell array anyway, so there's no need for the cellfun anyway.

Your correction for the cellfun example worked - thanks a lot!

flight_no = cellfun(@(s) s(~isspace(s)), flight_no, 'UniformOutput', false)
