    reading missing values in array?

    Ahn210 -- i'm glad you found a method that works for you salgerman -- thanks to you, too. just like mikrom, i also did not know about the TR descriptor. we learn something new every day :)

    reading missing values in array?

    something else to add to the above my suggestion AND the "string" suggestion should both work. my suggestion might be less tedious -- if you know in advance WHICH column has blank entries, WHERE (in the column) those blank entries are, etc otherwise, if you don't know that info in advance...

    reading missing values in array?

    xwb -- you are right ! i completely forgot that little detail ... i'm a bit rusty :( instead, try something like the following revised code :- DO I = 1 , N READ (1,*) A (I) BACKSPACE 1 IF ( A (I) == 85337 ) THEN READ (1,*) A (I), B (I) , C (I) , D (I) , E (I) , F (I) ELSE...

    reading missing values in array?

    do you know in advance :- 1) which column has missing values ? is it always column C ? 2) the value of A in each of the rows that have missing values ? is it always either 85337 or 85339 ? if so, then why not have something like :- DO I = 1 , N READ (1,*) A (I) IF ( A (I) == 85337 )...

    Multivariate normal pdf code?

    sorry this reply is so late please find below some fortran code that possibly does what you want -- multivariate normal pdf. i worked on a small project several years ago. part of it involved calculating the multivariate normal pdf. this is a sample of my code. it should help you get started...

    My FORTRAN code crashes on the 53 file, why?

    a subtle point to make you said :- "...works fine until I get to the 53rd time in the LOOP then it crashes." but, according to your code, there are 2 LOOPS where that could occur :- do k=1,60 end do and do i=1,1096 end do do you know WHICH of these loops is the culprit ? if it's...

    Time to say good bye ...

    hmmm, sounds to me like a fortran question :- PROGRAM PUB_SLOPE REAL :: SLOPE_1 REAL :: SLOPE_2 SLOPE_1 = slope from pub 1 to home SLOPE_2 = slope from pub 2 to home IF ( SLOPE_1 < 0.0 ) THEN GOTO pub 1 ELSE IF ( SLOPE_2 < 0.0 ) THEN GOTO pub 2 ELSE FIND another pub END IF sorry :)

    generate a matrix of possible combinations using fortran

    oops ! i forgot some "dimension" details ... the lines ?? ,INTENT (IN) :: X ?? ,INTENT (INOUT) :: B should instead be ?? ,INTENT (IN) :: X (9,2) ?? ,INTENT (INOUT) :: B (512,9)

    generate a matrix of possible combinations using fortran

    i "sort of" get what you are trying to do. but, your code seems to be doing 1 thing, and your "description" (of what you're trying to do) seems to want something else. regarding the nested do loops:- maybe you could try using a recursive subroutine (or recursive function) ? for example, see...

    Fortran 90, PUBLIC subroutines, and &quot;local&quot; variables within subroutines

    a quick note to all of you that replied. sorry if i haven't given you all of you a star (as a thanks). i did try to give you all a star, but, i don't think it worked properly, so maybe it only worked for a few of you. but yeah -- i did try to give everyone a star.

    Fortran 90, PUBLIC subroutines, and &quot;local&quot; variables within subroutines

    Norbert (and others) :- i'm not using gfortran. i'm using intel visual fortran composer xe. FJacq :- by "no" do you mean that only a subroutine is made PUBLIC, and it's local variables are not ALSO made PUBLIC ? Norbert (and others) :- about the automatic deallocation of allocatable arrays. as...

    Fortran 90, PUBLIC subroutines, and &quot;local&quot; variables within subroutines

    thanks for your replies. first, i'll just go back a step, and explain one detail i left out of my original post. i said my subroutines have the attribute PUBLIC. by this i mean:- a) each subroutine is stored in it's own module, b) each module contains one (and only one) subroutine, c) in each...

    Fortran 90, PUBLIC subroutines, and &quot;local&quot; variables within subroutines

    i'm using Fortran 90. i use lots of subroutines (each of which are given the PUBLIC attribute). in most of these subroutines i'm using ALLOCATABLE matrices -- which are "locally within" each subroutine. for ease of programming, i've thought of a "universal" way of naming INTEGER variables...

    fortran 90/95, recursive subroutines, and optional arguments

    i'm using fortran 90/95. i'm using recursive subroutines. i want to use an optional argument within one of these subroutines. i'm trying to determine whether i can. basically, i want to know if the following situation is valid :- 1) a recursive subroutine has the optional argument declared...
