I have a matrix that's been read into the program and I need to plot the mean and standard deviation over all users against time for the data.
Can someone help me figure out how to plot that?

How have you imported the data. What format is it in?
Need to see code and ideally attach the data if you can please. Then happy to answer.

Assuming time varies by row and user varies by column, here's a demo you can follow.
% Create a matrix of measurements of users (columns) across time (rows)
m = randn(100,10).*(rand(1,10)*3) + randi(10,1,10);
% Compute the mean and standard dev for each column
mu = mean(m,1,'omitnan');
sd = std(m,[],1,'omitnan');
% Plot results
figure()
% show raw data
h1 = plot((1:numel(mu))-.2, m, 'k+', 'Color', [.7 .7 .7], 'MarkerSize',3, 'DisplayName','raw data');
hold on
% Show mean and std
h2 = errorbar(1:numel(mu), mu, sd, 'o', 'linewidth', 1.5, 'color', 'k', 'DisplayName', 'Mean & std');
% cosmetics
xlabel('User')
ylabel('Measurement (units)')
xlim([0,numel(mu)+1])
legend([h1(1),h2(1)])
