Hi all,

I have been trying my hand at matlab recently and encountered an error while attempting to solve an ordinary differential equation. The equation I am trying to solve is in the picture attached.

I am getting like this after running this code

clear all;
clc;
close all;
syms g(x) u(t) x1(t) x2(t) x3(t) x4(t) x5(t) x6(t) x7(t) x8(t) x9(t) x10(t);
g(x)=exp(40*x)+x-1;
A =[-g(x1)-g(x1-x2)+exp(-t); g(x1-x2)-g(x2-x3);g(x2-x3)-g(x3-x4);g(x3-x4)-g(x4-x5);g(x4-x5)-g(x5-x6);g(x5-x6)-g(x6-x7);g(x6-x7)-g(x7-x8);g(x7-x8)-g(x8-x9);g(x8-x9)-g(x9-x10);g(x9-x10)]
ode1 = diff(x1,t)==[-g(x1)-g(x1-x2)];
ode2=  diff(x2,t)== g(x1-x2)-g(x2-x3);
ode3=  diff(x3,t)== g(x2-x3)-g(x3-x4);
ode4=  diff(x4,t)== g(x3-x4)-g(x4-x5);
ode5=  diff(x5,t)== g(x4-x5)-g(x5-x6);
ode6=  diff(x6,t)== g(x5-x6)-g(x6-x7);
ode7=  diff(x7,t)== g(x6-x7)-g(x7-x8);
ode8=  diff(x8,t)== g(x7-x8)-g(x8-x9);
ode9=  diff(x9,t)== g(x8-x9)-g(x9-x10);
ode10= diff(x10,t)== g(x9-x10);
odes=[ode1;ode2;ode3;ode4;ode5;ode6;ode7;ode8;ode9;ode10]
S = dsolve(odes)
