MATLAB: Pulling .mat files from multiple directories in one function

Question

I'm writing a function that pulls data from one directory, compares it's string name to another file in another directory and then runs processes on them both

So far things look like this

function matlabanswers_plzhelp
eData= dir('C:/file/file/file/*.mat')
for i = 1:numel(eData)
eName = eData.name
a=regexp(eName,'_','split');
experimentName = a{1};
load(eName)
lData = dir('C:/differentfolder/*.mat')
for n=1:numel(lData)
lName = lData.name
if strcmp(lName,experimentName) ==1
 load lName
% run code using variables from both loaded eName and lName.mat files
else
end
end
end

For some reason this type of code works when I'm working out of one directory, but refuses to actually load the files if they are from different directories…

any idea of what I'm doing wrong?

Thanks ML

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
