Inverse hyperbolic sine



Y = asinh(X) returns the inverse hyperbolic sine of the elements of X. The function accepts both real and complex inputs. All angles are in radians.

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 -5x5.

x = -5:.01:5;

Input Arguments

collapse all

Hyperbolic sine of angle, specified as a scalar, vector, matrix, multidimensional array, table, or timetable. The asinh operation is element-wise when X is nonscalar.

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