When you call load, you are not referencing them by their file name only (i.e. no directory). Try something like this:
function matlabanswers_plzhelp
d1 = ['C:/file/file/file/'];
eData= dir([d1 '*.mat'])
for i = 1:numel(eData)
eName = eData.name
a=regexp(eName,'_','split');
experimentName = a{1};
load([d1 eName])
d2 = 'C:/differentfolder/';
lData = dir([d2 '*.mat'])
for n=1:numel(lData)
lName = lData.name
if strcmp(lName,experimentName) ==1
load([d2 lName])
% run code using variables from both loaded eName and lName.mat files
else
end
end
