Titel: For Loop Issue - Need Help
|
 |
I am trying to do a very simple FOR loop command, but having some problem
What I want is - for example -
x = has gane of values
dx = 0.1
y = x + dx
z = y + xy
The way I want is, x has a range of values, say 1:0.1:2; I like take the first value, which is 1 and plug it in y-equation, i.e. y = 1+0.1= 1.1, then take the value 1.1 and plug it again in y-equation, and get y-value, and insert it again in the y-equation. I like to run this til the end valu of x. i.e 2
However, when value of y=1.1, it will automatic calculate z, and then, when y=1.2, it will plug in to z-equation automatic.
When first value of z is calucated it will go back and take next 2nd value of x=1.1, and calulate y, then z. The loop will continue and will not take random value of x, it will take 1st value, the 2nd valu, then 3rd value of x, and calculate all y and z .
Hope someone can tell me how to do it.
Thanks.

i think most will have a Problem to understand your case here, as i do myself.
however, if i understood it Right, you want to first run the loop only with the first equation, and after it is done, with the 2nd (?)
in that case, just make 2 loops, tho i dont see the Benefit here.

I have used FOR loop, however, it always pick up random values from "x".
For example, I want x=1.1, then x=1.2, then x=1.3 ...til x=2
The code I tried :
x_range = 1:0.1:2;
x = x_range(randi(numel(x_range)));
The code above is wrong, as it always pick up ranrom values.
I want it should pick up values in sequence.
Can anyone advice me what to do?

can you paste your entire code in here and using the code button, so the readability is better.
i may think whats going on here, but i am not 100% sure.
i may completly dont understand hat u wanna achieve here, but the example you showed ... is done by simple
i dont see the point of using randi, when you dont want to have randomness.
