Suppose A is the matrix. You can convert it to the table using the following lines of code:
T = array2table(A);
% Default heading for the columns will be A1, A2 and so on.
% You can assign the specific headings to your table in the following manner
T.Properties.VariableNames(1:4) = {'Q25_1','Q25_2','Q25_3','Q25_4'}

Slightly simpler, you can write this in one line:
T = array2table(A,'VariableNames',{'Q25_1','Q25_2','Q25_3','Q25_4'});

This code doesn't work with heterogenous matrix. Do you know how to convert a 12x7 matrix into a table and then into an excel document? I need to title the columns with days of the week and the rows with times from 9:00am to 8:00 pm.

@David Logan, is it possible to also give the rows a name as well on the side? Just like how the columns have a heading above them

RowNames
A = randi([-1 99], 12, 7); %some sample data
today = dateshift(datetime('now','format', 'hh:mm a'), 'start', 'day');
rt = today + hours(9:20).';
cn = dateshift(today, 'start', 'week') + caldays(0:6);
cn.Format = 'eeee';
dn = string(cn);
T = array2timetable(A, 'rowtimes', rt, 'VariableNames', dn);
T
It was deliberate that I use datetime operations to calculate the names of the days of the week, so that the day names will appear in whatever language is suitable for your area.
Note however, that if your region's "first day of the week" is monday instead of Sunday, then I do not know what order the days will come out as -- and I do not know what order the array happens to have its days in. You might need to circshift(dn) or something like that.
