psMathType* psBinaryOp (  psPtr  out, const psPtr  in1, const char *  op, const psPtr  in2 )

Perform simple binary arithmetic with images or vectors. Performs addition, subtraction, multiplication, division, power, minumum, and maximum arithmetic operations with images and vectors. Uses the form: out = in1 op in2, Where op is: "=", "+", "-", "*", "/", "^", "min", or "max" This function only supports vector-vector or image-image operations. Returns: psType* : Pointer to either psImage or psVector. Parameters: out  Output type, either psImage or psVector. in1  First input, either psImage or psVector. op  Operator. in2  Second input, either psImage or psVector.

psMathType* psUnaryOp (  psPtr  out, const psPtr  in, const char *  op )

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. Returns: psType* : Pointer to either psImage or psVector. Parameters: out  Output type, either psImage or psVector. in  Input, either psImage or psVector. op  Operator.
