i need 4d plot for any range

if true
u1=1;
u2=1;
u3=1;
u4=1;
a=0.1;
b=0.5;
g=0.25;
t=1;
A=12.*b.^2.*u3./u2;
v=(b.^2.*u1+4.*b.^4.*u3+g.*u4)./b;
x= -20:1:20;
y= -20:1:20;
z = -20:1:20;
u = A./(cosh(a.*x+b.*y+g.*z-v.*t).^2);
surf(x,y,z,u); 
colorbar
end

Best Answer

vol3d('cdata', u)
and also pass [-20,20] for the Xdata, Ydata, and Zdata parameters
vol3d is from the file exchange
