sinh(x), x REAL or a structure with REAL components |

sinh(x) returns the hyperbolic sine of the elements of x, when x is a REAL scalar, vector, matrix or array. The result has the same shape as x. In terms of other functions, sinh(x) = (exp(x) - exp(-x))/2. If any element of x is MISSING or > 710.4758600739439 in absolute value, the corresponding element of sinh(x) is MISSING and a warning message is printed. When x is a structure, all of whose non-structure components are REAL, sinh(x) is a structure of the same shape and with the same component names as x, with each non-structure component transformed by sinh(). See topic 'transformations' for more information on sinh().
