problem building sygvx

[wilcox__nigel]

I am using the following call

call sygvx(K,M,d,,,,,,il,iu)

and get the following build error

Error: a null argument exisits in a subroutine CALL or in a function reference. [DSYGVX_MKL95]

if I just use call sygvx(K,M,d) then it builds fine, but I do not want to calculate all eigenvalues

What am I doing wrong?

Thanks

Nigel

Hello, Nigel,

I think,
call sygvx(K,M,d,il=il,iu=iu)
could help you.

Thanks,
