MATLAB: Rename function inside MATLAB script

functionname

I have one generic script that calls in several times a function, which I want to be changing the name in an easy way. My idea would be to change the name of the variable in the upper part of the script and that it directly changes in all the script. The structure of my idea would be the following:
FunctionName = 'newName';
    [...code...]
 @(data,h)FunctionName(data,h)
    [...code...]
How would that be possible?
Many thanks

One way assuming your input is a string:
FunctionName = 'newName';
     :
FunctionHandle = str2func(FunctionName);
f = @(data,h)FunctionHandle(data,h);
Or, if you want to use function handles from the start:
FunctionName = @newName;
     :
f = @(data,h)FunctionName(data,h);
