Method one:
A = 10 * ones(4)
Method two:
A(1:4,1:4) = 10
Method three:
A = 10 + zeros(4)
Method four:
A = repmat(10,4,4)
Method five:
A = [10,10,10,10;10,10,10,10;10,10,10,10;10,10,10,10]
Method six:
A(4,4) = 0;
A(:) = 10
Method seven:
A = bsxfun(@plus,[1,1,1,1],[9;9;9;9])
Method eight:
A = [10;10;10;10]*[1,1,1,1]
Method nine:
A = 10.^ones(4)
Method ten:
A = toeplitz([10,10,10,10],[10,10,10,10])
Method eleven:
A = round(real(ones(4)^2.660965))
Method twelve:
A = mod(10,zeros(4))
Method thirteen:
A = accumarray([1,1],10,[4,4],@sum,10)

Already there as Method Three :)
I avoided 9+ones(4) though, for being basically the same thing.

And still another possibility:
A = randi([10 10], 4, 4);
