Function Log(x)

# Log

Log(
x             ! (input) numerical expression
)


## Arguments

x

A scalar numerical expression in the range $$(0,\infty)$$.

## Return Value

The function Log returns the natural logarithm $$\ln(x)$$.

Note

• A run-time error results if x is outside the range $$(0,\infty)$$.

• The function Log can be used in constraints of nonlinear mathematical programs.
