syms f(x)
sym x
f(x)=2*x^2
x=0;
v=[];
diary('wispn.txt')
diary on
while x<0.36
I=int(f,0,x)
x=x+0.1;
v(t)=w(x,I)
t=t+1;
end
diary off

A simple approach is
syms f(x)
sym x
f(x) = 2*x^2;
xv = 0; % x is name of sym variable
I = [];
while xv(end) < 0.36
I(end+1) = int(f,x, 0, xv(end));
xv(end+1) = xv(end) + 0.1;
end
xv(end) = [];
plot(xv, I);
