Is error a function?

Use the ISERROR function to see if a cell contains any error message, including #N/A, #VALUE!, #REF!, #DIV/0!, #NUM!, #NAME?, or #NULL! For example, =ISERROR(A1) will return TRUE if A1 is is displaying an one of the errors mentioned above , and FALSE if not.

What does ERF mean in Symbolab?

error functionis the “error function” encountered in integrating the normal distribution (which is a normalized form of the Gaussian function). It is an entire function defined by.

Why is it called error function?

In 1871 J. W. Glaisher wrote that “Erf(x) may fairly claim at present to rank in importance next to the trigonometrical and logarithmic functions.” Glaisher introduced the symbol Erf and the name error function for a particular form of the law as follows: … But this quote sounds like Glaisher arbitrarily picked the name.

What is a erf number?

An erf number is the number used to describe the property purchased. When a property or erf is sold, the transaction is then recorded by the Registrar of Deeds.

How does Matlab calculate relative error?

To compute the relative error (assuming you’re trying to find a stationary point of the function), after computing ff, subtract ff from x and take the absolute value. Then maybe you should divide that by the absolute value of x, but that depends on how you define relative error.

What does ERF stand for in property?

From Wikipedia, the free encyclopedia. In real estate, an erf (pl. erven) is the legal term used in Namibia, South Africa and Eswatini to describe a piece of land registered in a deeds registry as an erf, lot, plot or stand. The term is of Afrikaans origin.

What is ERFC Matlab?

erfc( x ) returns the Complementary Error Function evaluated for each element of x . Use the erfc function to replace 1 – erf(x) for greater accuracy when erf(x) is close to 1 .

What is the inverse error function?

1. Introduction. The inverse error function inverf x occurs in the solution of nonlinear heat and diffusion problems [ 1 ]. It provides exact solutions when the diffu- sion coefficient is concentration dependent, and may be used to solve certain moving interface problems.

What is erf in math?

In mathematics, the error function (also called the Gauss error function), often denoted by erf, is a complex function of a complex variable defined as: This integral is a special (non-elementary) sigmoid function that occurs often in probability, statistics, and partial differential equations.

What is the error function used for?

The error function erf is a special function. It is widely used in statistical computations for instance, where it is also known as the standard normal cumulative probability. The complementary error function is defined as erfc ( x ) = 1 − erf ( x ) .
