while ~exist('A', 'var') && ~isnumeric(A)
   ...
end
This will continue to loop until A is assigned a value and the value is numeric.
The common kinds of values that are not numeric include logical values, character strings, structures, cell arrays, function handles, graphics objects (R2014b or later), and various other kinds of objects.
