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)

What about: 10 + zeros(4) ? ;-)

[Stephen23]

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);

+1 Very cunning! That made me laugh out loud :)

Thank you!
