Izabela,
It is difficult to tell what's happening without seeing the function code.
However, it appears as if variable p_x were cleared or redefined to have
only 5 components prior to the assignment of two of its elements (those
with indices 1 and 5) when executing the formula.
What I would do is to create a new function removing all function code
not related to the problem, trying to track what happens to p_x before
applying the formula.
Regards,
Federico Miyara

Hello,
I have a strange problem with simple calculations which are done
inside a function. I will put here exact data and formula:
p_x=
0.
0.
0.
0.
0.
0.
p_x_pocz=
0.
0.
0.
0.
0.
0.
reakcje=
1. 1.03 2.1 -2.1 1. 2.
4. 0.92 2.45 -2.45 5. 2.
luzne_nr=
1.
4.
u=
4.6
3.6
-2.4
-4.4
-1.4
l_poziom=
5.1
4.56
p_x(reakcje(:,5))=p_x_pocz(reakcje(:,5))+u(luzne_nr).*reakcje(:,2)./l_poziom;
When it is calculated inside the function I get a result:
p_x=
0.93
0.
0.
0.
-0.89
When I use the same data and formula in the Console I get a correct
result:
p_x =
0.93
0.
0.
0.
-0.89
0.
To check the input values I displayed the input data before the
formula in the function with disp, and then I used these values for
calculations in the Console.
Has andybody any idea what can be wrong? Am I missing something?
Thanks for any help.
Kind regards,
Iza
