How to convert the type string to the type MeritOperandType in Matlab?

I have a problem about ZOS-API in Matlab.
Could we transform a MFE operator like 'REAY' in the type String to  ZOSAPI.Editors.MFE.MeritOperandType.REAY in Matlab? 

Coud we do the the same thing like the following code for C#?

 MeritOperandType mfOP;

String OP='REAY';
mfOP = (MeritOperandType)Enum.Parse(typeof(MeritOperandType),OP, true);
