Hi, I need to print out a statement that has multiple looping variables with different iterations. I am pretty sure I cannot use the "for" loop statement here, but i'm unsure what else I can do. I need to print (probably using fprintf) iterations of something like this:

ELSE IF (TIME(1) <= 3.419999e+00 ) THEN

FLUX(1)=AMG*EXP(-2*(((COORDS(3)+V*TIME(1)- 6.498 )**2+(COORDS(1)- 0.2484 )**2)/(R**2)) FLUX(2)=0.0

The numbers in bold are my 3 variables. The first number (3.419999e+10) increases by a value of 0.001579 per increment, the second number (6.498) increases by 0.0012 per increment and the third increases by 0.0009 per increment. The next statement should read:

ELSE IF (TIME(1) <= 3.421578e+00 ) THEN

FLUX(1)=AMG*EXP(-2*(((COORDS(3)+V*TIME(1)- 6.4992 )**2+(COORDS(1)- 0.2493 )**2)/(R**2)) FLUX(2)=0.0

Can anyone show me how to create 3 different variables, with different iterations per loop step? Thank you!!!

if i understand your question correctly, you can use a for loop. a simple example:

a = 3.419999e+00;
b = 6.498;
c = 0.2484;
a_inc = 0.001579;
b_inc = 0.0012;
c_inc = 0.0009;
for i=0:10
    a_current = a+i*a_inc;
    b_current = b+i*b_inc;
    c_current = c+i*c_inc;
    disp(['(a,b,c) = ' num2str([a_current b_current c_current])])
end
