Syntax

tf = isscalingunspecified(a)
tf = isscalingunspecified(T)

Description

example

tf = isscalingunspecified(a) returns 1 (true) if fi object a has a fixed-point or scaled double data type and its scaling has not been specified.

example

tf = isscalingunspecified(T) returns 1 (true) if numerictype object T has a fixed-point or scaled double data type and its scaling has not been specified.

Create a numerictype object and determine whether it has unspecified scaling.

T1 = numerictype(0)
T1 =


          DataTypeMode: Fixed-point: unspecified scaling
            Signedness: Unsigned
            WordLength: 16

tf = isscalingunspecified(T1)
tf = logical
   1


T2 = numerictype(0,24,12,'DataType','ScaledDouble')
T2 =


          DataTypeMode: Scaled double: binary point scaling
            Signedness: Unsigned
            WordLength: 24
        FractionLength: 12

tf = isscalingunspecified(T2)
tf = logical
   0

Create a fi object and determine whether it has unspecified scaling.

a = fi(pi,1)
a =

          DataTypeMode: Fixed-point: binary point scaling
            Signedness: Signed
            WordLength: 16
        FractionLength: 13

tf = isscalingunspecified(a)
tf = logical
