I want to solve the integral.

I want to solve the integral.

What you want to find here is the amount value. However, the CE value is a value that is partially taken from the value of another function. So I organized my code like this:

function damountdt = Columnfun_KH_0223(Q_E,C1_total)
C_E1=repmat(C1_total(1:425,101), 1, 1);
damountdt = 1.27*C_E1;
end

However, the amount does not appear in the workspace.

function damountdt = Columnfun_KH_0223(Q_E,C1_total)

That says that whatever value is written to the variable named damountdt will be returned to the calling routine.

However, your code never writes anything to that variable. It writes to C_E1 and uses C_E1 after that. It writes to damount_E1dt but never uses that variable.

However, the amount does not appear in the workspace.

Which variable are you expecting to appear, and in which workspace?

thank you for the reply. I want a variable called 'amount' to appear in the workspace. After reading your answer, you asked me to indicate C_E1 first, but I did not understand correctly.
