integ(A,B) Performs numerical integration of the expression A by B. Calculation is performed
as follows.
When n = 1, α
n
= 0
When n > 1, α
n
is defined as follows:
where,
α
n
: integral of A for the index number n
y
i
: A value for the index number i
x
i
: B value for the index number i
If A or B contain some invalid values, the invalid values are ignored for the
calculation.
For subor
dinate sweep, the first index number of each primary sweep is always 1.
Example
C=integ(A,B)
Data type A, B: vector or numeric, C: vector.
isValid(A) Returns 1 if the expression A is valid and is not double.NaN, or else returns 0.
Example
B=isValid(A)
Data type A: numeric, B: numeric.
lgt(A) Returns the logarithm (base 10) of the expression A.
If A=0, -Overflow is returned
with the status “Arithmetic error”.
If A is a negative value, the logarithm of the absolute value is returned with the
status “Arithmetic erro
r”.
Example
B=lgt(A)
Data type A: numeric, B: numeric. Or A: vector, B: vector.
