Hey there, I'm trying to generate a streamline plot but I keep getting an error message saying something is wrong at line 14. Can anybody help?
edit: Sorry, I forgot to mention that the streamlines vary with time so I'll probably be recording multiple plots

Ran in:
[X,Y] = meshgrid(-5:0.1:5,-5:0.1:5) ;
u = X.*(1+2*Y) ;
v = Y ;
streamslice(X,Y,u,v)

So I think I may have figured it out
clc; clear all; close all
syms x y u v t c
u(x,y,t) = x*(1+2*t); %defined as a function of x, y, and t since streamline is time varying in this case
v(x,y,t) = y;
St = int(u,y)==int(v,x)
St(x, y, t) = 
figure(1) %for plotting the streamlines
[x y] = meshgrid(-5:0.1:5 -5:0.1:5);
t = 0;
u2 = u(x,y,t); %remember to keep "t"
v2 = v(x,y,t);
streamslice(x,y,u2,v2)
title('t = 0') %rinse and repeat for as many time intervals as needed
xlabel('x')
ylabel('y')
figure(2)
[x y] = meshgrid(-5:0.1:5 -5:0.1:5);
t = 0.5;
u2 = u(x,y,t);
v2 = v(x,y,t);
streamslice(x,y,u2,v2)
title('t = 0.5')
xlabel('x')
ylabel('y')
