Concatenation of multiple variables into one variable

I do have multiple variables in .mat file. Size of each variable is 1x33376. I need to concatenate all the variables into one variable, Then exclude the NaN values and find the mean of all values vertically.

Assuming that the mat file contains only these variables:

data=cell2mat(struct2cell(load('filename.mat')));
meanvals=nanmean(data);

Thank you..

In my mat file, I do have files named A_... and B_....I need to find seperate mean for both excluding Not A Number (NaN).

I got the following error, when I tried the code.

Error in ==> Variablemerging1 at 1 data=cell2mat(struct2cell(load('OutA2011.mat')));

Can you please help me?

Now, should the variables be concatenated or do you want the mean for every variable? nanmean will ignore NaN, so something like

nanmean([nan 1 2;3 nan 4])

will return [3 1 3].

If you want the mean of every single variable, then you want the mean of the second dimension, right (as the size in first dimension is 1, mean does not make too much sense). So if you want the mean for each variable, just use

meanvals=nanmean(data,2);
