Let's say I have a table with n rows and z columns. Columns represent different variables and rows each time point. Now I would like to calculate a mean for each variable over specific ranges of n (e.g. continuously for rows 1:300:end). Could you please help? I am kind of lost...

There are several ways to do this in MATLAB. Following shows one option
M = rand(900, 10);
C = mat2cell(M, 300*ones(size(M,1)/300,1), size(M,2));
M_mean = cell2mat(cellfun(@mean, C, 'uni', 0));
or this
M_mean = squeeze(mean(reshape(M, 300, size(M,1)/300, [])))
