passing a filename as argument in matlab -

in matlab have function should take in file name. file has struct in it, later file should executed in function struct loaded work space.

for example:

my function hello(a), 'a' file name, file has struct.

on executing file in command window struct loaded in workspace. same way want struct loaded in workspace when call function.

i tried eval(a), not loading struct in file workspace.

from file name how obtain struct name, though know there struct in file, going vary dynamically.

so how should return structure in function?

i not sure whether want struct (or structs) inside file copied automatically workspace, or if want assign data yourself.

the following solution copies variables file a "base"-workspace automatically using assignin() function. solution assumes give file .mat file.

function hello(a)    all_structs = load('-mat', a);    var_names = fieldnames(all_structs);    k = 1:length(var_names)       assignin('base', var_names{k}, all_structs.(var_names{k}));    end end
