If there are positive values for y in the range of 0 to infinity, then the output i.e. The output can also be in the form of vector, matrix, scalar or multi-dimensional array. It can handle single and double data types with complex number support. The input argument of a logarithmic equation can be represented in the form of a vector, scalar, matrix or multi-dimensional array.

If the result contains an imaginary part, then it ranges from – π to π. If the input argument type is of floating-point, then the output is also floating-point. If y is given in the form of an integer, then it is given by equation log(1/y) =-log(y).If y is not a positive integer, then it is represented as log(y) = i π + log (- y).If y is of the data type numeric then it is represented as log(e^y) =y+ai2π, where a is an integer and imaginary part of the result ranges from – π to π.There are several rules which should be followed while working with natural logarithmic equations: The natural logarithm is also defined for all the complex numbers where y is not equal to 0. In Matlab, natural logarithm is given by log(y) which represents the natural logarithm of y. Hadoop, Data Science, Statistics & others So, we should be careful while using a base in any logarithmic equation. The value of e is given by 2.71828 and it is also denoted by a log. While if the base of the logarithmic equation is represented using e (also known as Euler’s number), then it is known as a natural logarithm. If a logarithmic equation is written without base, then it is considered to have based as 10 and is known as a common logarithm. The base of the logarithmic equation can be changed depending on the case. Natural logarithms form an important topic in Mathematics and Matlab.

Working of Natural Log in Matlab with Examples Now, if there is a question stating 2 raised to x power is 8 and our goal is to find x then we use logarithmic equation which is given by log2(8) =3, which is referred as log base 2 of 8 is 3.Here base is given as 2 and the exponent we got is 3. For example, 2 raised to power 3 will give 8 as the output, this can be represented by the exponential equation as 2^3 = 8. Logarithms are used in most mathematics, Physics or any domain-related to Calculus field. The logarithm is defined as the inverse of an exponential function. In this article, we will discuss Natural Log in Matlab.
