Rename Struct Fields Old Function

Hello,
I have a struct that has 20 different field names. Somewhere within these 20 names, it has a field name of B_in_ which I want to rename to B_m because I converted its value from inches to meters. I have found this function renameStructField, but it requires a scalar structure for the renaming. I tried this:
a="B_in_"
b="B_m"
FullTable=renameStructField(FullTable,a,b)
Interestingly if I were to do isscalar(a), and isscalar(b) they both return 1 which means they are both scalars. However, it still throws the scalar structure error.
Anyone know why this does not work, and how to make it work?
Thank you,
Luck

the question is not if your fieldnames are scalar but if the struct is scalar. you will not have any problems if the atruct has multiple fields but is one dimensional:
myStructScalar.inIn=5;
renameStructField(myStructScalar,'inIn','inM')
but if your struct is not scalar, this will not work directly
myStruct(1).inIn=2
myStruct(2).inIn=6
renameStructField(myStruct,'inIn','inM')
jowever you can vreate a new field and do the conversion in the same step and remove the old field afterwards
for structNr=1:numel(myStruct)
myStruct(structNr).inM=myStruct(structNr).inIn;
end
rmfield(myStruct,'inIn')
