# acotd

Inverse cotangent in degrees

## Description

example

Y = acotd(X) returns the inverse cotangent (cot-1) of the elements of X in degrees. The function's domain and range include complex values. For real elements of X in the range [-Inf,Inf], acotd returns values in the range [-90,90]. For complex values of X, acotd returns complex values.

### Inverse Cotangent of Vector

x = [0 20 Inf];
y = acotd(x)
y =

90.0000    2.8624         0

The acotd operation is element-wise when you pass a vector, matrix, or N-D array.

### X — Cotangent of anglescalar value | vector | matrix | N-D array

Cotangent of angle, specified as a real-valued or complex-valued scalar, vector, matrix, or N-D array. The acotd operation is element-wise when X is non-scalar.

Data Types: single | double
Complex Number Support: Yes

### Y — Angle in degreesscalar value | vector | matrix | N-D array

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