Syntax

tf = isscaleddouble(a)
tf = isscaleddouble(T)

Description

example

tf = isscaleddouble(a) returns 1 (true) when the DataType property of fi object a is ScaledDouble. Otherwise, it returns 0 (false).

example

tf = isscaleddouble(T) returns 1 (true) when the DataType property of numerictype object T is ScaledDouble. Otherwise, it returns 0 (false).
