Function/Subroutine Documentation

create_linear_solver_block()

subroutine sll_m_linear_solver_block::create_linear_solver_block ( class(sll_t_linear_solver_block), intent(inout)  self, integer(kind=i32), intent(in)  n_block_rows, integer(kind=i32), intent(in)  n_block_cols  )

private

creates a linear solver_block you must sets the linop using set

Parameters

[in,out]	self	the current object
[in]	n_block_rows	number of row blocks
[in]	n_block_cols	number of col blocks

free_linear_solver_block()

subroutine sll_m_linear_solver_block::free_linear_solver_block ( class(sll_t_linear_solver_block), intent(inout)  self )

private

destroys the current object

Parameters

[in,out]

self

the current object

Definition at line 250 of file sll_m_linear_solver_block.F90.

print_info_linear_solver_block()

subroutine sll_m_linear_solver_block::print_info_linear_solver_block ( class(sll_t_linear_solver_block), intent(in)  self )

private

prints the current object

Parameters

[in]

self

the current object

read_from_file_linear_solver_block()

subroutine sll_m_linear_solver_block::read_from_file_linear_solver_block ( class(sll_t_linear_solver_block), intent(inout)  self, character(len=*), intent(in)  filename  )

private

Definition at line 157 of file sll_m_linear_solver_block.F90.

set_linear_solver_block()

subroutine sll_m_linear_solver_block::set_linear_solver_block ( class(sll_t_linear_solver_block), intent(inout)  self, integer(kind=i32), intent(in)  i_block_row, integer(kind=i32), intent(in)  i_block_col, class(sll_t_linear_solver_abstract), intent(in), target  linop, real(kind=f64), intent(in), optional  r_coeff  )

private

sets a linear solver

Parameters

[in,out]	self	the current object
[in]	i_block_row	the block row identifier
[in]	i_block_col	the block col identifier
[in]	linop	the associated linear solver
[in]	r_coeff	a real coefficient to associate to the entry block [optional]

Todo:

use linop % n_rows/cols instead of n_global_rows/cols
