Hi Hassan,
I understand that you are trying to solve a first order ODE using a derivative function. The function that you have provided has some syntactical and variable issues due to which you are getting the error message.
You may refer to the following modified code to resolve the errors:
function dCdt = F_O2(x);
kLa = x(1);
c1 = x(2);
t = 300;
Ce = 100;
dCdt = (kLa*Ce-c1)/t;
end
Based on your code and the inputs you are providing, your input variable "x" should be at least a two - dimensional vector for your code to work. An example call to the function would be:
F_O2([1 2])
You may also refer to this documentation for solving ODEs : https://www.mathworks.com/help/matlab/ref/ode.html
