Bode diagram command is not working

I used to plot the bode diagram using these commands, and now its not working. Which toolbox I should download

  s = tf('s');
    H=100/(s+100)
    bode(H);grid;

First please go into detail abouot what ‘not working’ means.

If it worked before, it should still work.

Run this:

which bode -all

from a script or your Command Window.

The only results should be:

C:\Program Files\MATLAB\R2021a\toolbox\control\ctrlobsolete\bode.m
C:\Program Files\MATLAB\R2021a\toolbox\shared\controllib\engine\@DynamicSystem\bode.m  % Shadowed DynamicSystem method

If anything else appears, such as indicating that ‘bode is a variable’, that is likely the problem. The solution is to rename whatever is causing the problem to some name that does not cause problems.
