## Complementary Error Function

• Compute the first and second derivatives of the complementary error function:syms x diff(erfc(x), x) diff(erfc(x), x, 2)ans = -(2*exp(-x^2))/pi^(1/2) ans = (4*x*exp(-x^2))/pi^(1/2)Compute the integrals of these expressions:syms x int(erfc(-1, x), x)ans

If you want to compute the complementary error function for a complex number, use sym to convert that number to a symbolic object, and then call erfc for that symbolic object.For Error Function Table Because these numbers are not symbolic objects, you get the floating-point results:A = [erf(1/2), erf(1.41), erf(sqrt(2))]A = 0.5205 0.9539 0.9545Compute the error function for the same numbers converted to symbolic objects.

Example: 'File not found.' msgID -- Identifier for errorcharacter vector Identifier for the error, specified as a character vector. For floating-point arguments, erf returns floating-point results. MathWorks does not warrant, and disclaims all liability for, the accuracy, suitability, or fitness for purpose of the translation. For -1 and 1, erfinv returns -Inf and Inf, respectively.erfinv([-2 -1 1 2]) ans = NaN -Inf Inf NaN Find the inverse error function of the elements of a matrix.M =

Complementary Error Function Compute the error function for x and sin(x) + x*exp(x):syms x f = sin(x) + x*exp(x); erf(x) erf(f)ans = erf(x) ans = erf(sin(x) + x*exp(x))Error Function for Vectors and Matrices If Erfc Matlab You can also select a location from the following list: Americas Canada (English) United States (English) Europe Belgium (English) Denmark (English) Deutschland (Deutsch) España (Español) Finland (English) France (Français) Ireland (English)

For more information, see Tall Arrays.TipsFor expressions of the form erfinv(1-x), use the complementary inverse error function erfcinv instead. have a peek at these guys Discover... This message displays as the error message. When x is close to 1, then 1 - x is a small number and may be rounded down to 0. Erf Function Calculator

The resulting code is about three times faster in execution, but is considerably less accurate.

Error Function Excel The identifier must always contain a colon and follows this simple format: component:mnemonic. The implemented exact values are: erf(0) = 0, erf(∞) = 1, erf(-∞) = -1, erf(i ∞) = i ∞, and erf(-i ∞) = -i ∞.
