ply_calculate_coeff_strip Subroutine

private subroutine ply_calculate_coeff_strip(n, s, gam, matrix, alph, nDiagonals, block_offset, remainder, strip_lb, strip_ub, subblockingWidth)

Arguments

Type IntentOptional Attributes Name
integer, intent(in) :: n
integer, intent(in) :: s
real(kind=rk), intent(inout) :: gam(:)

Modal coefficients of the Chebyshev expansion. Size has to be: (1:indeps*params%n,nVars)

Note, that the resulting array will have changed layout, and the transformed direction will run slowest in the array.
real(kind=rk), intent(in) :: matrix(:,:)

The arraz that holds the coefficients to calculate.
real(kind=rk), intent(in) :: alph(:)

Modal coefficients of the Legendre expansion. Size has to be: (1:params%n*indeps,nVars)

The direction which is to be transformed has to run fastest in the array.
integer, intent(in) :: nDiagonals

The number of diagonals to calculcate
integer, intent(in) :: block_offset

The offset of the block relative to the origin of the whole matrix.
integer, intent(in) :: remainder

The diagonals that are not covered by any block.
integer, intent(in) :: strip_lb

The lower bound of the strip to calculate.
integer, intent(in) :: strip_ub

The upper bound of the strip to calculate.
integer, intent(in) :: subblockingWidth

The subblocking width defines the size of the blocking of the diagonal strides, i.e. in y direction. This subblocking is used to get a better cache locality.
