cscd

Cosecant of argument in degrees

Syntax

Y = cscd(X)

Description

Y = cscd(X) returns the cosecant of the elements of X, which are expressed in degrees.

Examples

Cosecant of 180 Degrees Compared to Cosecant of π Radians

cscd(180) is infinite, whereas csc(pi) is large but finite.

cscd(180)

ans = 
Inf

csc(pi)

ans = 
8.1656e+15

Cosecant of Vector of Complex Angles, Specified in Degrees

z = [35+i 15+2i 10+3i];
y = cscd(z)

y = 1×3 complex

   1.7421 - 0.0434i   3.7970 - 0.4944i   5.2857 - 1.5681i

Input Arguments

X — Angle in degrees

scalar value | vector | matrix | multidimensional array | table | timetable

Angle in degrees, specified as a real-valued or complex-valued scalar, vector, matrix, multidimensional array, table, or timetable. The cscd operation is element-wise when X is nonscalar.

Data Types: single | double | table | timetable
Complex Number Support: Yes

Output Arguments

Y — Cosecant of angle

scalar value | vector | matrix | multidimensional array | table | timetable

Cosecant of angle, returned as a real-valued or complex-valued scalar, vector, matrix, multidimensional array, table, or timetable of the same size as X.

Extended Capabilities

Tall Arrays

Calculate with arrays that have more rows than fit in memory.

The cscd function fully supports tall arrays. For more information, see Tall Arrays.

C/C++ Code Generation

Generate C and C++ code using MATLAB® Coder™.

Usage notes and limitations:

• In some cases, generated code returns -Inf when MATLAB^® returns Inf.

• In some cases, generated code returns Inf when MATLAB returns -Inf.

Thread-Based Environment

Run code in the background using MATLAB® backgroundPool or accelerate code with Parallel Computing Toolbox™ ThreadPool.

This function fully supports thread-based environments. For more information, see Run MATLAB Functions in Thread-Based Environment.

GPU Arrays

Accelerate code by running on a graphics processing unit (GPU) using Parallel Computing Toolbox™.

The cscd 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).

Distributed Arrays

Partition large arrays across the combined memory of your cluster using 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 R2006a

R2023a: Perform calculations directly on tables and timetables

The cscd 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.
