[CSC 335] Fortraners....

[Andrew J. Pounds]

Hey -- I noticed that most of you that turned in the homework last week 
did it correctly, but if you are going to be using the LAPACK routines 
you must remember that Fortran is column major and not row major in how 
it stores matrices.

Row major..

for (i=0; i<10; i++) {
     for (j=0; j<10; j++) {
         a[i][j] = calculation;
     }
}

Column major...

do i=1, 10
    do j = 1, 10
        a(j,i) = calculation
    enddo
enddo
