There are 5 variables in a folder (crate1, crate2, crate3, crate4, crate5). Each of these variables have 3 sub-variables inside them. The 3 sub-variables have same names but different values, for all the variables. For example, crate1 has month, time, date. Crate2 also has month, time, date. And so on up to crate5... The task needed is to divide sub-variables (only month and time) by 0.5, for all the variables crate1 to crate5... Instead of doing it manually one after other, is there a way I could do for all at same time?

"The task needed is to divide sub-variables (only month and time) by 0.5..."
Multiplying by two is probably clearer.

For scalar variables,
S=dir('crate*.mat');
month = arrayfun(@(s) load(s.name).month, S)/0.5;
time = arrayfun(@(s) load(s.name).time, S)/0.5;
EDIT: For non-scalar variables,
S=dir('crate*.mat');
month = cell2mat( arrayfun(@(s) load(s.name).month, S','uni',0) )/0.5;
time = cell2mat(arrayfun(@(s) load(s.name).time, S','uni',0) )/0.5;
