The LOG function returns the logarithm of a number to the base you specify, and the LOG10 returns the base -10 logarithm of a number.

The log-likelihood is just the (natural, usually) logarithm of the ordinary likelihood function. It is numerically easier to work with, and since log is a monotonic function, equivalent.<BR><BR ...

Lin-Log: impedance-versus-temperature (thermistor data). Using the built-in “linterp” function, MathCAD estimates and plots the data (Figure 1). As you can see, at X coordinates between the original ...

Unless you want a very rough estimate of a log function, you are going to need to just punch this in your calculator (or use a log-table where you look up a value).

Logharmonic function: A function incorporating logarithmic terms within its formulation, leading to a non-linear differential equation that extends the classical harmonic framework.

Harmonic mappings and logharmonic functions occupy a central role in complex analysis and applied mathematics. Harmonic mappings are functions that satisfy Laplace’s equation and are frequently ...
