Functions/Subroutines
subroutine	math_ext::copy_mask (a, b, size, mask, mask_size)
	Copy within a mask. NOTE, this differs from masked_copy in the indexing. \( a_i = b_i, for i in mask \).
subroutine	math_ext::cadd_mask (a, c, size, mask, mask_size)
	Add a constant to a masked vector. \( a_i = a_i + c, for i in mask \).
subroutine	math_ext::invcol1_mask (a, size, mask, mask_size)
	Invert a masked vector. \( a_i = 1/a_i, for i in mask \).
subroutine	math_ext::cmult_mask (a, c, size, mask, mask_size)
	Multiply a masked vector by a constant. \( a_i = c * a_i, for i in mask \).
subroutine	math_ext::col2_mask (a, b, size, mask, mask_size)
	Multiply 2 masked vectors. Save the result in a new vector. \( a_i = b_i * c_i, for i in mask \).
subroutine	math_ext::col3_mask (a, b, c, size, mask, mask_size)
	Multiply 2 masked vectors. Save the result in a new vector. \( a_i = b_i * c_i, for i in mask \).
subroutine	math_ext::sub3_mask (a, b, c, size, mask, mask_size)
	Subtract 2 masked vectors. Save the result in a new vector. \( a_i = b_i - c_i, for i in mask \).
real(kind=rp) function	math_ext::glsc2_mask (a, b, size, mask, mask_size)
	Weighted inner product \( a^T b \) for indices in the mask.
