## How do you calculate natural log in Matlab?

Y = log( X ) returns the natural logarithm ln(x) of each element in array X . If you want negative and complex numbers to return error messages rather than return complex results, use reallog instead.

**What base is log10 in Matlab?**

base 10

log10( x ) returns the logarithm to the base 10 of x .

**How do you write logs in Matlab?**

You don’t have to define the base. Just write log(14-y). In matlab , log(x) means ln(x). Sign in to answer this question.

### How do you use log in MATLAB?

Y = log10( X ) returns the common logarithm of each element in array X . The function accepts both real and complex inputs. For real values of X in the interval (0, Inf ), log10 returns real values in the interval ( -Inf , Inf ). For complex and negative real values of X , the log10 function returns complex values.

**How do you read a log table?**

Q4: How do you read a log table? A: Take the first 2 digits of the number irrespective of the decimal and look for the row with that number. Next look for the column number corresponding to the third digit of the number. You may also need to look into the mean difference table to get the final value.
