For the record, algorithms in the following areas were
first written in machine code, from the mid-1940s,
and run from the early 1950s.

Differential equations
solving linear equations
latent roots
matrix multiplication
calculate determinants
matrix transpose
matrix inversion
linear porogramming
multple linear regression
statistical tabulations.
input and output
floating-point arithmetic (software)

Most were part of the General Interpretive Programme,
developed at National Physical Laboratory by 1955.

In particular, 129 simultaneous equations solved on Pilot ACE in 1952.
Simultaneous equations and second-order differential equations were solved,
and are documented in proceedings of 1953 NPL symposium.
Aircraft flutter design calculations were done in 1952 with the introduction of jet
aeroplanes -- made compulsory in 1954 following investigations of
crashes of the Comet (the investigation itself required extensive computer calculations).
Crystallography calculations from 1954.

Just to mention a few ...
