I want to apply for postdoc(Europe),so I need to write a research plan.I do not know how much should I go into details.The subject is geophysics,also it will be different from what I have done for my PhD.Should I cite the people from Stanford for example.Like Mavko shows this ,I am going to...

I have a problem with something that should be very simple,I do not no if it is programming issue or my ignorance. If I have matrix c(5,5) 3 0 0 0 0 1 2 0 0 0 0 1 2 0 0 0 0 1 4 1 0 0 0 1 2 and vector b(1,2,3,4,5) c*b=a a=(3,5,8,24,14) FORTRAN MATMUL C=MATMUL(B,A) Correct?

Yes,I am creating input file where velocities need to be calculated for every node.Total number of velocities in model is 1484,quite big. Regarding software,I have problem to install SUPER Lu from LBNL,are there any links for simple code that to not require libraries(like BLAS( IN THIS CASE?

I have Ax=b problem where A 1484x1484 matrix,b 1484x1. A is sparse(95% zeros) but if I go for LU decomposition what should be the next step? Or is there any other method,I forgot algebra,learned it when I was undergrad long time ago.

I have a crooked line of data points,want to project data on the straight line.If I go standard least-square method,some of the points change their position to each other,this is not want I a want.Anyone has idea about regresion methods or some other statistics,except classical y=bx+c.

Thanks,but I prefer something more maths related,like I give input data and get image.

I have problem like this:recetengular cells,each of the cells should be colored.I have tried with NCL-NcCAR but it is too complicated to write script for me and I do not want to waste time.Can anyone tell me about free software?

Ok,I need to put this. dik=Vi-Xk and represents Eucleadean norm Derivative with respect to Vi.

I have problem like attached.

I am dealing with a problem,which can be formulated Ax=B,in the first place I wanted to solve it with conjugate gradient method.BUt A is not positive definite.Which are the other iterative options in this case?

FC= ifort LD = ifort -align all FCFLAGS = -O2 -g -ipo -traceback -warn noalign LDFLAGS = $(FCFLAGS) # Executables nray: main.o findnode.o plots.o segmnt.o empty.o aldone.o erase.o pcolor.o box.o plot.o axtick.o axis.o line.o pltsrcbox.o find.o dot.o grad.o intersect.o straight.o...

It calculates arrays apr1dsens and apr2dsens over 2 loops,I do not how to define as1 and as2.This way It gives stupid results on the output.

Hi I have problems with passing arrays from module to the main code.My module: module s2em contains c --------------------------- subroutine sensd2emod_mod1(iper,as1,as2) c --------------------------- c Sensitivities of the E-mode impedances with respect to...

I have problems with my code.As a result of calculation I got rank2 l(21,1) array.Due to the THE ITERATIVE PROCESS I will get the same array in every iteration.How to allocate values and use them later.Should I create new array like do iter=1,n lbig(iter,nmax,1)=l(nmax,1)?

do i=1,iter l(nc)=l(nc,iter) end do I tried the above but it doesn't work.l is vector dimension 21,every iteration gives me l.I do not know the number of iterations.How to store l for every iteration?
