MKL_SPARSE_?_QR invalid input error (Fortran)

Hello,

I am experimenting the Sparse QR library to solve a linear system of equations. When I run the attached file, I get the following output:

The last output "3" indicates "SPARSE_STATUS_INVALID_VALUE The input parameters contain an invalid value."

Can anyone help?

you put the input parameters

you put the input parameters into wriong order, fixing that, you will see the correct answer:

!stat = MKL_SPARSE_S_QR (SPARSE_OPERATION_NON_TRANSPOSE, csrA, descrA, SPARSE_LAYOUT_ROW_MAJOR, x, cols, ldx, b, ldb)
stat = MKL_SPARSE_S_QR (SPARSE_OPERATION_NON_TRANSPOSE, csrA, descrA, SPARSE_LAYOUT_ROW_MAJOR, cols, x, ldx, b, ldb)
