log, ln

Natural logarithm (base e).

Syntax

log(expr)

ln(expr)

Argument

expr
A valid scalar, vector, or matrix expression.

Example

Templex Expression Result
{ln(1)} 0
{log({1, 2, 2.71828})} 0, .6931, 1
{log({ {1, 2 }, {4, 8}})} {0, 0.693147},{1.38629, 2.07944}
Curve Math Vectors
x = c1.x

y = log(c1.x)

Comments

If expr is a scalar, the result is a scalar which is the natural logarithm of expr. expr must be positive.

If expr is a vector, the result is a vector containing the natural logarithm of each element in expr. Each element of expr must be positive.

If expr is a matrix, the result is a matrix containing the natural logarithm of each element in expr. Each element of expr must be positive.
