MATLAB: Namespaces for variables, several measurements

Question

It would be nice if Matlab would have a namespace feature. I have several logfiles which have some variables, for instance

voltage1, voltage2, current1, current2.

This measurement has been repeated several times, but this creates a problem if you want to load all the files that variables get overwritten. Thus you have to create custom variables. It would be nice if if was possible to load the variables like this in one load command:

measurement_set1/voltage1
measurement_set1/voltage2
measurement_set1/current1 etc.

and the other

measurement_set2/voltage1
measurement_set1/voltage2

And acces them in this way. Or is there another fast way to do this?

Answer 1

measurement_set1 = load('File1.mat');
measurement_set2 = load('File2.mat');
measurement_set1.voltage1
measurement_set1.voltage2
measurement_set1.current1
measurement_set2.voltage1
measurement_set2.voltage2
