Hello Guys,

I would like to ask about, how to plot the results from the dsolve equation?. Here is my code that I used

Rmax = 1410.34;

conc = 500e-9;

ka = 3.46e3;

kd = 1.46e-4;

t = linspace(0, 1800, 600)';

A = ka*conc*Rmax;

B = ka*conc;

C = kd;

syms y(t) A B C

eqn = diff(y,t) == A-B*y-C*y;

cond = y(0) == 0;

s(t) = dsolve(eqn,cond);

fplot(t(:),s)

在 MATLAB Online 中打开

Rmax = 1410.34;                                           
conc = 500e-9;                    
ka   = 3.46e3; 
kd   = 1.46e-4; 
A = ka*conc*Rmax;
B = ka*conc;
C = kd;
syms t y(t)
eqn = diff(y,t) == A-B*y-C*y;
cond = y(0) == 0;
s(t) = dsolve(eqn,cond);
s = matlabFunction(s);
t   = linspace(0, 1800, 600)';
plot(t,s(t))
