Ran in:
In version 2025b:
syms a b c x
f = a*x^2+b*x+c
f = 
gives error message:
Error using replace
Too many input arguments
This used to work fine (at least up to version 2023a, I also noted the issue in version 2024b).
Any idea what's going wrong anyone?

I'm confused.
The usual MATLAB "replace" function seems to be shadowed by another function "replace" with the same name, but this shadowing function is not listed in your output from
which replace -all
Do you know of a function with name "replace.m" that you've created and that is saved somewhere on your MATLAB path ?

@Henri
What shows up if you command
dbtype 'C:\Program Files\MATLAB\R2025b\toolbox\matlab\strfun\replace.m' 1:3
Also, try
which replace('ab','a','c')

@Torsten Hopp indeed, another replace.m in my Matlab path, that's embarrassing having warned students about this kind of thing for the last 35 years... So, all sorted. Thank you all for your contributions!
