+% DESCRIPTION: VALIDATE checks that the input Analysis Object is
+%              reproducible and valid.
+%
+% CALL:        b = validate(a)
+%
+% INPUTS:      a - a vector, matrix or cell array of Analysis Objects
+%
+% OUTPUTS:     b - a vector, matrix or cell array of logical results:
+%              0 - input object failed
+%              1 - input object passed
