MATLAB: Using regular expressions to identify names and unit from string

You could do it in two steps, like this:

str='name1/name2 [C]'
%%Extract unit, if there is one
exp=']|[|}|{';
id=regexp(str,exp);
if isempty(id)==0
    unit=str(id(1)+1:id(2)-1)
end
%%Extract name
exp='/| ';
id=regexp(str,exp);
if numel(id)==2
    name1=str(1:id(1)-1)
    name2=str(id(1)+1:id(2)-1)
else
    name1=str(1:id(1)-1)
    name2=str(id(1)+1:end)
end

If you do not want to save whatever is within the curly brackets as units, then remove those from the first expression.

MATLAB: Problem with a string .

What does "here is my string" exactly mean? Strings do not contain the surrounding quotes. They appear only, if e.g. a cell string is printed to the command window:

C = {'string'};
disp(C)

Therefore I assume this is enough:

S = 'abc "abc" ';
S = strrep(S, '"', char(39));
fprintf('%s\n', S);

I use char(39) because it looks less strange than '''', but both create exactly the same: one quote character.
