Complex vector arithmetic

["Liam Healy" <liam@......................>]

I notice that some vector functions on complex numbers do not exist,
though I can't think of a reason for this.  For example, these do not exist:

gsl_vector_complex_add
gsl_vector_complex_float_add
gsl_vector_complex_long_double_add

but all real types do, as well as the corresponding matrix functions:

gsl_matrix_complex_add
gsl_matrix_complex_float_add
gsl_matrix_complex_long_double_add

I made a table of arithmetic functions and definitions I could find in
the library:
    	  	    real vector	real matrix	complex vector  complex matrix
_add	  	    yes	       	yes  		no	   	   yes
_sub	  	    yes	       	yes		no		   yes
_mul	  	    yes		no		no		   no
_mul_elements	    no		yes		no		   yes
_div		    yes		no		no		   no
_div_elements	    no		yes		no		   yes
_scale		    yes		no		no		   yes
_add_constant	    yes		no		no		   yes

I can see that _mul_elements or _dev_elements is used only for
matrices and _mul or _div used only for vectors, but I cannot see why
vectors do not have definitions for complex types but matrices do.

Is there a reason for the absence of definitions for complex vectors?
