Automatically create variations of the same variable?

I have this code. At the moment there are only three check boxes giving the option for Type 1, 2 and 3. Multiple can be selected at once.

% mat(1 through to 3) = zeros(4,16);

if app.chkType1.Value == 1
    mat1 = xlsread('Matrices.xlsx','C3:R6');
end
if app.chkType2.Value == 1
    mat2 = xlsread('Matrices.xlsx','C9:R12');
end
if app.chkType3.Value == 1
    mat3 = xlsread('Matrices.xlsx','C15:R18');
end

% sum mat(1 through to 3)

How can I write this, so that it automatically assigns numbers to the mat title?

i.e, I could maunually write out:

mat1 = zeros(4,16);

mat2 = zeros(4,16);

mat3 = zeros(4,16);

How can I write this in a single line, such that if I had 100 check boxes rather than 3, I would not have to write out 100 lines of zeros?

Thank you

Do not use separate variables. use a cell array. You can have a table of range entries and loop through a list of check boxes, pulling out the range and xlsread() and assign into the cell array

Thank you, I have managed to achieve it through using cell arrays
