Calling Sequence

erf(x)

Parameters

x

-

array or algebraic expression

Description

• 

The error function is defined as

erfx=20xⅇt2ⅆtπ

• 

erf(x) will evaluate by default only when the result is an exact value, or when the input x is a floating-point number.  When x is a symbolic expression, it will remain in function form so that it can be manipulated symbolically  or as part of a larger expression.  

• 

If x is an array, the result is an elementwise mapping over x.

• 

erfc(x) is the complementary error function, that is, 1erfx.
