I am trying to build a matrix, called A, which consists of blocks of smaller matrices along the diagonal and near-zero elements in the off-diagonal, in FreeFem v4.11 using the syntax:
dmatrix A(MatLinOp, clean=1, columns=Ji);
MatLinOp specifies the blocks going into the diagonal of A,
clean=1 makes sure the near-zero elements are identically zero and
Ji is just an index declaring the number of blocks going into matrix A.
If I execute this line in FreeFem v4.11, I get a compile error:
dmatrix The Identifier dmatrix does not exist Compile error: line number: 376, dmatrix
Is it because this syntax does no longer work in FreeFem v4.11?
Any help is greatly appreciated.
