Built-in Functions
This section describes Agilent EasyEXPERT built-in functions. The functions
appear in alphabetical order. In the function name, the character in parentheses is a
variable.
abs(A) Returns the absolute value of the expression A.
Example B=abs(A)
Data type A: numeric, B: numeric. Or A: vector, B: vector.
acos(A) Returns the arccosine value of the expression A. The A value must be between -1
and 1.
Example B=acos(A)
Data type A: numeric, B: numeric. Or A: vector, B: vector.
asin(A) Returns the arcsine value of the expression A. The A value must be between -1 and
1.
Example B=asin(A)
Data type A: numeric, B: numeric. Or A: vector, B: vector.
at(A,B) Finds a data element in the expression A, and returns the value. The data element is
specified by index B. The index number starts from 1. If B is not an integer, a linear
interpolated A value will be returned.
Example C=at(A,B)
Data type A: vector or numeric, B: numeric, C: vector.
at(A,B,C) Finds a data element in the expression A, and returns the value. The data element is
specified by the indices B and C. B is the index for the primary plane of a
two-dimensional array and C is the index for the secondary plane. The index number
starts from 1.
If B is not an integer, a linear interpolated A value will be returned. The linear
interpolation will be executed between A[n,C] and A[n+1,C], where n < B < n+1.
If C is not an integer, C will be n, where n < C < n+1.
Example D=at(A,B,C)
Data type A: vector or numeric, B: numeric, C: numeric, D: numeric.
