Re: Need a Fortran Function

that is a simple loop. You should be able to do that yourself..:)

Re: Need a Fortran Function

Function multMat(a,Mat,m,n) implicit double precision(a-h,o-z) DIMENSION Mat(m,n),multMat(m,n) !---------------------------------- DO i=1,m

DO j=1,n

multMat(i,j)=a*Mat(i,j)

ENDDO ENDDO

! or just multMat=a*Mat ! same as the above routine

end function

Re: Need a Fortran Function

If you don't write an index fortran consider it all. for example: mat = mat*s mat(i,:)=mat(i,:)*s mat(:,j)=mat(:,j)*s
