!! \brief Copy the upper triangle, i.e. all entries
|
||||
!! A(I,J) such that DIAG <= J-I
|
||||
!! default value is DIAG=0, i.e. upper triangle from
|
||||
!! the main diagonal up.
|
||||
!! DIAG= 1 means copy the strictly upper triangle
|
||||
!! DIAG=-1 means copy the upper triangle plus the first diagonal
|
||||
!! of the lower triangle.
|
||||
!! Moreover, apply a clipping by copying entries A(I,J) only if
|
||||
!! IMIN<=I<=IMAX
|
||||
!! JMIN<=J<=JMAX
|
||||
!! Optionally copies the lower triangle at the same time

|

!! \param jmin [1] minimum col index
