How to:
In MATLAB, there are several different logarithmic functions that are commonly used:
log(x) - This is what is sometimes called ln(x) or natural log, it has a base of 'e'
log2(x) - This is log with a base of 2
log10(x) - This is log with a base of 10
If we want to do computations using 'e' or the exponential:
exp(1) - This is 'e' by itself (raised to the 1st power)
exp(x) - This is 'e' raised to the 'x' power
Examples:
Let's first compute the log (base 10) of 10000:
log10(10000)
Now, let's find the value of the natural log of 'e' raised to the 8th power:
log(exp(8))
