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);

What is "the output"? You have used sprintf('%.3f') to create 3 decimal places, so thge reader can assume, that you can simply use the '%.2f' command. See: doc sprintf
In the documentation of num2str you find, that you cn use the same format specifier as in sprintf. See Walter's answer.

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)
corr=corrcoef(series_1,series_2);
num2str(corr(1,2),2)
% ^
tbl2 = {rand}
string(tbl2)
compose("%.2f", tbl2{:})
sprintf('%.2f', tbl2{:})
