asinh - Inverse hyperbolic sine - MATLAB (original) (raw)
Main Content
Syntax
Description
`Y` = asinh([X](#mw%5Ff2186df8-da5f-4556-9cdc-0f2a86d6620a))
returns the inverse hyperbolic sine of the elements of X
. The function accepts both real and complex inputs. All angles are in radians.
Examples
Find the inverse hyperbolic sine of the elements of vector X
. The asinh
function acts on X
element-wise.
X = [2 -3 1+2i]; Y = asinh(X)
Y = 1×3 complex
1.4436 + 0.0000i -1.8184 + 0.0000i 1.4694 + 1.0634i
Plot the inverse hyperbolic sine function over the interval -5≤x≤5.
x = -5:.01:5; plot(x,asinh(x)) grid on xlabel('x') ylabel('asinh(x)')
Input Arguments
Hyperbolic sine of angle, specified as a scalar, vector, matrix, multidimensional array, table, or timetable. The asinh
operation is element-wise whenX
is nonscalar.
Data Types: single
| double
| table
| timetable
Complex Number Support: Yes
More About
For real values x in the domain of all real numbers, the inverse hyperbolic sine satisfies
For complex numbers z=x+iy, the call asinh(z)
returns complex results.
Extended Capabilities
Theasinh
function fully supports tall arrays. For more information, see Tall Arrays.
The asinh
function fully supports GPU arrays. To run the function on a GPU, specify the input data as a gpuArray (Parallel Computing Toolbox). For more information, see Run MATLAB Functions on a GPU (Parallel Computing Toolbox).
Version History
Introduced before R2006a
The asinh
function can calculate on all variables within a table or timetable without indexing to access those variables. All variables must have data types that support the calculation. For more information, see Direct Calculations on Tables and Timetables.
