I'm currently trying to compute values of two different Variables, but the problem is that, while one equation is working, the other isn't. Here is my current code with my matrices included.
INITIAL MATRICES/ VECTORS:
X =
NaN
0.2200
0.3000
0.4400
0.4900
0.7000
0.8000
0.9000
1.1000
1.0000
1.1500
1.2000
1.2200
1.2600
1.2500
1.2700
1.2000
1.2200
1.2600
1.2000
1.2200

%% Problem 1
%{
X=Cell Mass Concentration (g/L)
U= Cell Mass Yield Per Carbon Monoxide gcells/mmolCO
t= Time (hours)
Mu= Specific Growth Rate
X1=X(1:end-1)
X2=X(2:end)
t1=t(1:end-1)
t2=t(2:end)
Mu=(X2-X1)/(t2-t1)
U=(X2-X1)/CO
%}
X1=X(1:end-1)
X2=X(2:end)
t1=t(1:end-1)
t2=t(2:end)
Mu=(log(X2)-log(X1))./(t2-t1);
U=(X2-X1)/CO;
%{
ans
Max value of Cell Mass Yield per Carbon Monoxide = max(Yx)
Max value of Cell Mass Concentration = max(Mu)
%}
% Find max values of specific growth rate(Mu) and cell mass yield(Yx/co)
Mumax=max(Mu);
Umax=max(U);
% Answer Display
sprintf('The maximum specific growth rate is %f, and the maximum cell mass yield per CO is %f',Mumax, Umax)
The problem with my current code is that, while Mu is equalling a vector which 26x1, U is equalling a matrix which is 25x26. I need U to also be a 26x1 vector, because currently my max value for U is 0.00000.

The ‘CO’ variable is missing.
If ‘CO’ is a row vector rathar than a column vector, that could be the problem. If so, the solution would be to transpose it to a column vector. Remember to do element-wise operations, if that is what you want.
