Synopsis

ABS(value)

Argument

value

One of the following: a constant; a variable; a formula evaluating to a single value; or an XV with only one item

Example

Given the following matrix items:

Column: A
Column: B
XV    : XVA: A
XV    : XVB: = = = B ^ 2

then the following are all valid uses of the function:

ABS(99)
ABS(A)

ABS(XVB)

Further information

ABS is not always differentiable and so alternative modeling approaches should be used where possible.
