asech
Inverse hyperbolic secant
Syntax
Description
Examples
Find the inverse hyperbolic secant of the elements of vector X
. The asech
function acts on X
element-wise.
X = [2 -3 1+2i]; Y = asech(X)
Y = 1×3 complex
0.0000 + 1.0472i 0.0000 + 1.9106i 0.3966 - 1.3845i
Plot the inverse hyperbolic secant function over the interval .
x = 0.01:0.001:1; plot(x,asech(x)) grid on xlabel('x') ylabel('asech(x)')
Input Arguments
Hyperbolic secant of angle, specified as a scalar, vector, matrix, multidimensional
array, table, or timetable. The asech
operation is element-wise when
X
is nonscalar.
Data Types: single
| double
| table
| timetable
Complex Number Support: Yes
More About
For real values in the domain , the inverse hyperbolic secant satisfies
For complex numbers as well as real values in the regions and , the call asech(z)
returns complex results.
Extended Capabilities
The
asech
function fully supports tall arrays. For more information,
see Tall Arrays.
C/C++ Code Generation
Generate C and C++ code using MATLAB® Coder™.
This function fully supports thread-based environments. For more information, see Run MATLAB Functions in Thread-Based Environment.
The asech
function
supports GPU array input with these usage notes and limitations:
If the output of the function running on the GPU can be complex, then you must explicitly specify its input arguments as complex. For more information, see Work with Complex Numbers on a GPU (Parallel Computing Toolbox).
For more information, see Run MATLAB Functions on a GPU (Parallel Computing Toolbox).
This function fully supports distributed arrays. For more information, see Run MATLAB Functions with Distributed Arrays (Parallel Computing Toolbox).
Version History
Introduced before R2006aThe asech
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.
