I am trying to store the values of each for loop iteration so I could plot them in respect to time. However, it keeps giving me the error:
Array indices must be positive integers or logical values.
Error in Rheology (line 16)
s_qtz(i) = A_qtz*(str.^n_qtz)*exp(-Ea_qtz/(R*i));
I am not quite sure of what to do to fix this error. I provided my code below.
%stress array
str = [0.1, 1, 10, 100];
%Constants
R = 8.314;
A_qtz = 1.26e-5;
n_qtz = 3;
Ea_qtz = 2.42e5;
%temp array
T = [973.15:100:1373.15];
for i = T
s_qtz(i) = A_qtz*(str.^n_qtz)*exp(-Ea_qtz/(R*i));
end
