Hi, This is a preliminary bug report, I'm trying a few things to check that. But so far, with nix, since gcc was upgraded from 13.2.0 to 13.3.0, test-cpp-contact-cholesky fail with big differences in some matrices (ie. 0.207 != 5e-17). I...
For the specific example below, four iterations are needed because the AEC, AWB, and LTM modules are selected. // Create a kernel: OCL_CHECK(err, cl::Kernel kernel(program, "ISPPipeline_accel", &err)); int loop_count = 4; for (int i = 0; i < loop_count; i++) { OCL_CHECK(...
The value of T2∗ is equal to the largest eigenvalue of ΣGT~ ; Β~ ΣG~ ; Β~ (or ΣΒT~; G~ ΣΒ~; G~ ). The sample permutation method is employed to calcu- late p-values. The sample permutation changes neither the correlation structure within gene sets nor the correl- ...
Testing the equality of the covariance matrices of two high-dimensional samples is a fundamental inference problem in statistics. Several tests have been p... J Wang,T Zhu,JT Zhang,... 被引量: 0发表: 2024年 TwoSampleTest.HD: An R Package for the Two-Sample Problem with High-Dimensional...

Both W n and W n s are n × n matrices, with their ( i j ) th elements being w i j = K h ( 〈 B , X i − X j 〉 ) / ∑ l ≠ i n K h ( 〈 B , X i − X l 〉 ) and ( w i j + w j i ) / 2 , respectively. To present the proof of Step...
where matricesM,GandKstand for the mass, gyroscopic and stiffness matrix of the model, respectively. The first mode shape and the corresponding eigenvalue are shown inFigure 7b. The critical speed estimation led to 18,295 rpm, which is beyond the system working range and it is considerably hi...
