function asinh
Returns the hyperbolic arcus sine of its argument, which can be either real, complex or a matrix. By default, the returned value is in radians. This can be changed by specifying the switch /deg.
Syntax
result = asinh(X [, /deg])
Arguments
| X: | a number (integer, real, complex) or a matrix, specifying the hyperbolic sine of the angle to be returned. If X is a matrix, a matrix of the same size is returned where each element represents the result of the operation. |
Switches
| /deg: | The result will be in degrees |
Examples
To find the angle (in degrees) whose hyperbolic sine is 0.5, type:
print asinh(0.5, /deg)
