Okay, so it turns out that I need to keep 'known' and 'free', but I can't seem to get this to work out for me. I'm still filtering through the same NF_array (which can be changed based on user input), but now I'm trying to keep the known and free in the matrix. Below is what I'm trying to do... Thanks for the help.
NF_array = [{'1, known, known, 0.0, 0.0'}, ...
{'8, known, known, 0.0, 0.0'}, ...
{'4, free, known, 0.0, 0.0' }, ...
{'5, free, known, 0.0, 0.0' }];
%Code I'm trying to use
syms known free %defining known and free in the program
NF_array = S(NF_2:NL_2);
optf = {'Delimiter',',', 'CollectOutput',true};
fmtf = '%f%s%s%f%f';
strf = sprintf('%s\n',NF_array{:});
outf = textscan(strf,fmtf,optf{:});
Nodal_Fixity = outf{1};
Nodal_Fixity = sortrows(Nodal_Fixity)
%What I'm getting... So I need columns 2:5 to populate still
Nodal_Fixity =
1
4
5
8
%(Need the code to process NF_array and convert to)%
Nodal_Fixity =
[ 1, known, known, 0, 0]
[ 4, known, known, 0, 0]
[ 5, free, known, 0, 0]
[ 8, free, known, 0, 0]

NF_array = [{'1, known, known, 0.0, 0.0'}, ...
{'8, known, known, 0.0, 0.0'}, ...
{'4, free, known, 0.0, 0.0' }, ...
{'5, free, known, 0.0, 0.0' }];
Nodal_Fixity = cell(4,5);
for nr = 1:4
Nodal_Fixity(nr,:) = strsplit(NF_array{nr},',');
end
If you also need to remove the spaces, then follow that with
Nodal_Fixity = regexprep(Nodal_Fixity,' ','');
That does not need to be inside the loop; it will operate on the entire cell array.

Note:
- importing/storing numeric data as character/string and then converting it to numeric afterwards is going to be less efficient than importing it as numeric in the first place.
- Storing numeric data as scalar arrays in a cell array is much less efficient than storing it in a simple numeric array.
