Write a MATLAB function that will accept a cell array of strings and sort them into ascending order according to the lexicographic order of the ASCII character set.

Sure, here's an example function that takes in a cell array of strings and returns a sorted cell array:

function sortedStrings = sortStrings(strings)
% Sorts the input cell array of strings in ascending order using ASCII ordering

% Convert the cell array of strings to a matrix of ASCII codes
asciiCodes = double(strings);

% Sort the rows of the matrix in ascending order
sortedAscii = sortrows(asciiCodes);

% Convert the sorted matrix back to a cell array of strings
sortedStrings = cellstr(char(sortedAscii));

end

Here's an example usage:

>> strings = {'hello', 'world', 'foo', 'bar'};
>> sorted = sortStrings(strings)
sorted =
  1x4 cell array
    {'bar'}    {'foo'}    {'hello'}    {'world'}

Note that this function uses the `double` function to convert each string to a matrix of ASCII codes, then the `sortrows` function to sort the rows of the matrix in ascending order. Finally, it converts the sorted matrix back to a cell array of strings using `char` and `cellstr`.
