How to load a variable from a loop name mat ?

Hi, I would like to load a variable(like X) from a dynamic mat file I have this:

for n=1:4
load(['nano',num2str(n),'.mat']) (X);
do some work on the variable
end

Are you simply asking how to load a specific variable? E.g.,

variable_to_load = 'X';
for n=1:4
    load(['nano',num2str(n),'.mat'],variable_to_load);
    do some work on the variable
end

Another formulation you might consider is the following:

      y = load(['nano',num2str(n),'.mat'],variable_to_load);
      z = y.(variable_to_load);
      all downstream code then uses variable named z

This latter formulation has the advantage that your downstream code can use a variable name (in this case z) that is known to you up front, regardless of the actual variable name you picked to load.
