Error using plot Data must be numeric, datetime, duration or an array convertible to double. Error in prueba3 (line 12) plot(x,Vol);

I need to plot Vol, = 50*x^2*((6*cos(8*x))/625 - (24*x*sin(8*x))/625 + 3/250)

Tell me What's wrong? Please !

clear;

clc;

Ro=1; G=981; A1=100; A2=150; A3=125;

CC = input ('Ingrese la COMPLIANCIA (cm3/cmH2O)DEL PULMON C = ');

C= CC/981;

syms x;

Q = x+0.1*sin(8*x);

X=Q*x*(A1+A2-A3)/(A1*A3)-Q*x*A1*(A2-A3)/(C*Ro*G*A1*A3);

Acel=diff(X,2);

Vol = Acel.*(x.^2/2)*((A1*A3)/(A1+A2-A3));x = linspace(0,3,500);

disp(Vol);

plot(x,Vol);

I have no idea what you want ‘x’ to be.

Try this:

figure
fplot(Vol, [0 C]);

Make appropriate changes to define ‘x’ (defined here to go from 0 to ‘C’).
