![]() Visual studio 2010 and Intel Visual Fortran Compose XE 2011.5.221 But. Thanks.Linking Abaqus and Visual Studio and. It would be great if you guys can help to give some suggestions. I used the MKL ?trnlsp related routines without boundary constraints to conduct the fitting. It's obvious that the optimal a and b, in this case, should be 0 and 2 respectively, to minimize the objective function. I defined my objective function as f(x) = |g(fx1)-fx2|. I want to solve a nonlinear least square fitting problem to estimate a and b. g(x)=a(x^2) bx. I have two vectors working as the training data. traceback -ftrapuv -O2 -prec-div -prec-sqrt -debug all -fp-speculation=off ![]() Can someone shed some light on the above points and provide me with pointers on what could be going wrong? Any help is appreciated greatly.įC = ifort -ipo -unroll -fp-model strict -fp-stack-check -check all -fpe0 \ With the least error on the last vector and %1 error on the second vector norm. A sample output is given below for the norms of the columns of the resulting matrix block F,įortran code with MKL with the same block size However, after this projection the norms start to differ. However I ran into some problems, I checked the code and up to this point the results are more or less the same with MATLAB, for instance before performing this step, the norms of the columns of F(as given above) are almost the same, the relative error between MATLAB and MKL is on the order to 1e-13. How I implemented this is to, in some steps, namely,ġ.) compute Vfr^T*F by using dgemm and store the result in r_dummy2, direct codeĢ.) from previous operations I stored the matrix vector multiplication, Mf*Vfr so I am re-using that here transa = 'n'ģ.) do the block subtraction with a simple loop( I can also use blas 3 level routines with a identity matrix of PXP for this I guess.) v_scalar = -1.0_dbl ![]() tfBlock3 is also used to store intermediate results. For a projection operation, I should implementį is a block of vectors of size sz_fXP, and stored as tfBlock2 in the code. ![]()
