Are these functions not available independently of whether cutensor and/or cuquantum are available?

I ran the tests with the following options:

DUSE_CUDA=ON
DUSE_CUTENSOR=OFF
DUSE_CUQUANTUM=OFF

and got the result:

The following tests did not run:
	659 - BlockUniTensorTest.gpu_Trace (Skipped)
	712 - DenseUniTensorTest.gpu_Trace (Skipped)
	791 - ExpM.gpu_ExpM_test (Skipped)
	794 - Arnoldi.gpu_which_LM_test (Skipped)
	795 - Arnoldi.gpu_which_LR_test (Skipped)
	796 - Arnoldi.gpu_which_LI_test (Skipped)
	797 - Arnoldi.gpu_which_SM_test (Skipped)
	798 - Arnoldi.gpu_which_SR_test (Skipped)
	799 - Arnoldi.gpu_which_SI_test (Skipped)
	800 - Arnoldi.gpu_mat_type_real_test (Skipped)
	801 - Arnoldi.gpu_k1_test (Skipped)
	802 - Arnoldi.gpu_k_max (Skipped)
	803 - Arnoldi.gpu_smallest_dim (Skipped)

The following tests FAILED:
	793 - Lanczos_Gnd.gpu_Bk_Lanczos_Gnd_test (Failed)
	815 - Svd.gpu_U1_zeros_test (Failed)
	837 - linalg_Test.gpu_BkUt_Svd_truncate3 (Failed)
	838 - linalg_Test.gpu_BkUt_Qr1 (Failed)
	840 - linalg_Test.gpu_BkUt_expM (Failed)

Some tests still seem to fail here, is it related to this PR?

[IvanaGyro]

The failed tests you listed may be the bugs that haven't been addressed. Except 815 - Svd.gpu_U1_zeros_test, which was reported at #505. For the skipped tests, yes, they are not implemented whether cutensor and/or cuquantum are used or not.

I added the unimplemented functions in the Cytnx Development Roadmap to keep track of it for possible future implementation. I m not sure though if it is the right place to document unsupported functions.
