cosh(x) returns the hyperbolic cosine 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, cosh(x) = (exp(x) + exp(-x))/2. When any element of x is MISSING or > 710.4758600739439 in absolute value, the corresponding element of cosh(x) is MISSING and a warning message is printed. When x is a structure, all of whose non-structure components are REAL, cosh(x) is a structure of the same shape and with the same component names as x, with each non-structure component transformed by cosh().
