tand

Tangent of argument in degrees

Syntax

Y = tand(X)

Description

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

Examples

Tangent of 90 degrees compared to tangent of π/2 radians

tand(90)

ans = Inf

tan(pi/2)

ans = 1.6331e+16

tand(90) is infinite, whereas tan(pi/2) is large but finite.

Tangent of vector of complex angles, specified in degrees

z = [180+i 15+2i 10+3i];
y = tand(z)

y = 1×3 complex

   0.0000 + 0.0175i   0.2676 + 0.0374i   0.1758 + 0.0539i

Input Arguments

X — Angle in degrees

scalar value | vector | matrix | N-D array

Angle in degrees, specified as a real-valued or complex-valued scalar, vector, matrix, or N-D array. The tand operation is element-wise when X is nonscalar.

Data Types: single | double
Complex Number Support: Yes

Output Arguments

Y — Tangent of angle

scalar value | vector | matrix | N-D array

Tangent of angle, returned as a real-valued or complex-valued scalar, vector, matrix, or N-D array of the same size as X.

Extended Capabilities

Tall Arrays

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

This 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.
