I'm not familiar with these pip options, but I tried this and
got the
following output:
Using pip 25.2 from C:\Python313\Lib\site-packages\pip
(python 3.13)
ERROR: Could not find a version that satisfies the requirement
matplotlib (from versions: none)
ERROR: No matching distribution found for matplotlib
This means that pip can't find matching wheels. You would see
this error message at the end if you didn't have a network
connection. Assuming pip can reach pypi then it thinks that none
of these wheels is suitable:
https://pypi.org/project/matplotlib/#files
There seem to be wheels for 3.13 on Windows for amd64 and arm64.
Is it possible that you are on a 32 bit machine or using a 32 bit
build of python?

I'm using a 32-bit build of python:
>python
Python 3.13.3 (tags/v3.13.3:6280bb5, Apr 8 2025, 14:32:59) [MSC
v.1943 32 bit (Intel)] on win32
Then the problem is that matplotlib no longer provides prebuilt wheels
for 32 bit python on windows. The simplest fix is to install a 64 bit
build of python.

Thanks Oscar, that solved the problem.
(I had other issues doing this: I had to convert some DLLs from 32- to
64-bit. But as far as I know I have resolved them all.)
Best wishes
