MATLAB: How to round a result to two decimal places, Part 2

MATLAB

https://www.mathworks.com/matlabcentral/answers/308927-how-to-round-a-result-to-two-decimal-places
shows how to round the result to two decimal places.
Here what I would want Matlab to do is to round the display to two demical places.
(1) I have 
Fit = polyfit(series_1,series_2, 1);
theString = sprintf('(dependent variable) = %.3f*(independent variable) %.3f', Fit(1), Fit(2));
How can one let Matlab display only up to two demical places?
(2) I have 
corr=corrcoef(series_1,series_2);
num2str(corr(1,2),3)
How can one let Matlab display only up to two demical places?
(3) I have 
tbl=anova(mdl);
tbl2=table2cell(tbl('x1',4)) % Get F-statistics
tbl3=string(tbl2);

series_1 = 1:10;
series_2 = cos(rand(1,10));
Fit = polyfit(series_1,series_2, 1);
theString = sprintf('(dependent variable) = %.2f*(independent variable) %.2f', Fit(1), Fit(2));
%                                             ^                           ^
disp(theString)
(dependent variable) = 0.02*(independent variable) 0.70
corr=corrcoef(series_1,series_2);
num2str(corr(1,2),2)
ans = '0.6'
%                ^
tbl2 = {rand}
tbl2 = 1x1 cell array
    {[0.3002]}

string(tbl2)
ans = "0.30025"
compose("%.2f", tbl2{:})
ans = "0.30"
sprintf('%.2f', tbl2{:})
ans = '0.30'
