As part of an heat exchanger problem, we are given two unknowns $T_{cs}$ and $T_{fs}$ solving the following equations: $\forall (Q,U,F, m_c,m_f, C_c,C_f, \Sigma , T_{ce},T_{fe}) \in \mathbb{R_+^*}^{10}, Q = U \Sigma F \frac{T_{ce}-T_{fs} -T_{cs} +T_{fe}}{ln(\frac{T_{ce}-T_{fe}}{T_{cs}-T_{fs}})} =...
In mathematics, the logarithmic mean is a function of two non-negative numbers which is equal to their difference divided by the logarithm of their quotient.
This calculation is applicable in engineering problems involving heat and mass transfer.
== Definition ==
The logarithmic mean is defined symbolically as:
M
lm

In linear algebra, the Hermite normal form is an analogue of reduced echelon form for matrices over the integers Z. Just as reduced echelon form can be used to solve problems about the solution to the linear system Ax=b where x is in Rn, the Hermite normal form can solve problems about the solution to the linear system Ax=b where this time x is restricted to have integer coordinates only. Other applications of the Hermite normal form include integer programming, cryptography, and abstract algebra.

Various authors may prefer to talk about Hermite normal form in either row-style...

Proposal: rename "generalizedeigenvector" to "generalized-eigenvector"
Pledge originally initiated by WillG in this suggested tag wiki excerpt edit. I support this proposal since it's a common pratice to separate words with hyphens in tag names in order to increase readability, like ode, real-a...
