Octave Logarithm Functions

In this tutorial, we will learn Octave Logarithm Functions. Octave supports many logarithmic functions in-built.

Logarithm Functions

Some of the functions are as follows:

log
log10
log2
log1p

Logarithm Function	Description
log(X)	To compute the natural logarithm ln(X)
log2(X)	To compute the base-2 logarithm
log10(X)	To compute the base-2 logarithm
log1p(X)	To compute the value of log (1 + X) accurately in the neighborhood of zero.

Examples

>> % Example of natural logarithm
>>
>> log(e)
ans = 1
>> log(10)
ans = 2.3026
>> % Note that log is nautral logarithm of base e
>>
>> % Calling two functions
>> log(exp(4))
ans = 4
