MATLAB: How to convert fixed point definitions (for example ‘fixdt(0,32,1,-50)’ to ‘fixdt(‘ufix32_Bn50′)’)

How to convert fixed point definitions (for example 'fixdt(0,32,1,-50)' to 'fixdt('ufix32_Bn50')')?
This means I would like to get the 'DataTypeNameString' while I have the information about:
a = fixdt(Signed, WordLength, SlopeAdjustmentFactor, FixedExponent, Bias)

Best Answer

This can be done by an undocumented method of the class which is created while calling 'fixdt'.
Please be aware, that this method can be removed in a future release and if there are any issues while using it, our support is limited.
Here is the workflow:
Create the data type:
a = fixdt(0,32,1,-50)
Now you can get the 'DataTypeNameString' with the following:
a.tostringInternalSlName
Which will result in:
ans = 'ufix32_Bn50'
