move ptr to imag data in mxArray to separate_full and separate_sparse classes * mex.cc (class mxArray_separate_full): Move separate pointer to imaginary array data here from mxArray_base_full along with all functions that operate on the on the separate array. (class mxArray_separate_sparse): Move separate pointer to imaginary array data here from mxArray_base_sparse along with all functions that operate on the on the separate array. (mxArray_base_full::fp_to_ov): New template to simplify the as_octave_value function. (mxArray_base_sparse::to_ov): New template to simplify the as_octave_value function.
