IMAG  IMAG Imaginary Function


Usage
 
 Returns the imaginary part of the input array for all elements.  The 
 general syntax for its use is
 
    y = imag(x)
 
 where x is an n-dimensional array of numerical type.  The output 
 is the same numerical type as the input, unless the input is complex
 or dcomplex.  For complex inputs, the imaginary part is a floating
 point array, so that the return type is float.  For dcomplex
 inputs, the imaginary part is a double precision floating point array, so that
 the return type is double.  The imag function returns zeros for 
 real and integer types.
