How do I write the number 0.5 into a complex double of size <401x1 complex double>

How can write a number 0.5 repetitively into a complex double of size 401x1 complex double?

[Walter Roberson]

A = complex(0.5 * ones(401,1));

Note: when you use this in an expression, if there are no complex components in the result of the expression, then the complex component will be dropped.
