# complex number & sort

*From*: "nakisa" <nakisa.nooraee@xxxxxxxxx>*Date*: 19 Mar 2007 06:32:18 -0700

hi everbody , i have 3 questions :

1) i know how complex number must be written in fortran . but now i

want to

calculate complex number in loop and use its value for other parts ,

my problem is

with complex number in loop . for example , i guess with this way i

can

work with complex numbers :

complex m

do i=1,10,1

m=(i,i)

end do

this program doesn't work .what can i do ?

2) i have an array with dimensioins A(3,200) . i want to sort these

array

with increasing the second row data algebrically . in fortran

libarary i can't

find suitable program , all program are for vectors .can anybody

propose me a way ?

3) in my program , numbers are calculated with 6 digits precesion

after point .( for example 21.938495 ) how

can i control the precesion ? i want it computes with 3 or 2 digits

after point .

best ,nakisa

.
