COSH Function

Calculates the hyperbolic cosine of the input variable.

result = COSH(x)

x The angle, in radians, that is evaluated.

result The hyperbolic cosine of x.

None.

COSH is defined by:

cosh(x) (e ^x + e ^-x)/2

If x is of double-precision floating-point data type, or of complex type, COSH yields a result of the same type. All other data types yield a single-precision floating-point result.

If x is an array, the result of COSH has the same dimensions, with each element containing the hyperbolic cosine of the corresponding element of x.

x = [0.3, 0.5, 0.7, 0.9]
