To generate one 4-by-4 matrix with a specific value you can use various approaches
Value = 3 ;
A = repmat(Value,4,4)
B = Value * ones(4,4)
C = zeros(4,4), C(:) = Value
You have to think about how to store several of these matrices. As planes in 3D arrays or, for instance, as cells in a cell array? The first option can only be used when all 2D matrices have the same size
Values = [3 6 99] ;
N = numel(Values)
Array3D = zeros(4,4,N) % a 4-by-4-by-3 3D array
for k=1:N
Array3D(:,:,k) = Values(k)
end
or in a cell array
Values = [7 -3 5 4]
CellArray = arrayfun(@(x) repmat(x,4,4),Values,'un',0)
disp(CellArray{1})
