Line vector + row vector = array works in r2017a but not in r2016a

I use the + operator in my r2017a version to sum a line vector and a row vector to give me an array.

A = [1 2]

B = [1;2]

C = A + B = [2 3; 3 4]

I tried to run my code on an other computer with the r2016a version but it doesn't work.

How can I simply do this command?

FYI this behavior is known as implicit expansion and was added to the arithmetic operators like + in release R2016b.

For older versions use bsxfun instead

C = bsxfun(@plus,A,B)
