 *  @brief Provides unary functions for simple matrix and vector element operations. Functions
 *  include:
 *
 *      Addition (+)
 *      Subtraction (-)
 *      Multiplication (*)
 *      Division (/)
 *      Power (^)
 *      Minimum (min)
 *      Maximum (max)
 *      Absolute value (abs)
 *      Exponent (exp)
 *      Natural Log (ln)
 *      Power of 10 (ten)
 *      Log (log)
 *      Sine (sin or dsin)
 *      Cosine (cos or dcos)
 *      Tangent (tan or dtan)
 *      Arcsine (asin or dasin)
 *      Arccosine (acos or dacos)
 *      Arctan (atan or datan)
 *
 *  Currently only vector-vector and image-image binary operations are supported.

/** Perform simple unary arithmetic with images or vectors
 *
 *  Performs absolute value, exponent, natural log, power of 10, log, sine, cosine, tangent, arcsine,
 *  arccosine, or arctan. operations with images and vectors. Uses the form:
 *
 *     out = op(in),
 *
 *     Where op is: "abs", "exp", "ln", "ten", "log", "sin", "cos", "tan" "asin", "acos", "atan", "dsin",
 *                  "dcos", dtan", "dasin", "dacos", or "datan".
 *
 *  Trigometric Operations with "d" prefix use units of degrees. Those without are in radians.
 *
 *  This function only supports vector-vector or image-image opertions.
 *
 *  @return  psType* : Pointer to either psImage or psVector.
