/**
|
|
* Calculate the exponent of a value.
|
|
* For matrices, the function is evaluated element wise.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.exp(x)
|
|
*
|
|
* Examples:
|
|
*
|
|
* math.exp(2) // returns number 7.3890560989306495
|
|
* math.pow(math.e, 2) // returns number 7.3890560989306495
|
|
* math.log(math.exp(2)) // returns number 2
|
|
*
|
|
* math.exp([1, 2, 3])
|
|
* // returns Array [
|
|
* // 2.718281828459045,
|
|
* // 7.3890560989306495,
