Getting "Error: This statement is incomplete."
显示 更早的评论
Hello. This is my code and I keep getting the error "This statement is incomplete." several times throughout but can't find the mistake.
6
figure (6);
v1 = [1 0 -5 0 0 4];
k=1;
for i=[-3 : 0.2 : 3]
p1 (k) = polyval(v1,i);
k = k+1;
j=1;
for i=[-3 : 0.2 : 3]
if i >= 0
v2 (j) = i^3;
j = j+1;
else if i < 0
v2 (j) = i^3 * (-1);
j = j+1;
end
end
end
plot (p1); grid on; hold on;
plot (v2);
Here's the errors:

The given code works fine.......is there any code before figure(6)?

There is no end for the first for loop. You start a second for i without an end for the first.
You seem to be missing end of the first for loop. Use this simplified code:
figure;
v1 = [1 0 -5 0 0 4];
i=-3:0.2:3;
p1 = polyval(v1,i);
v2=zeros(1,numel(i));
v2(i>=0) = i(i>=0).^3;
v2(i<0) = i(i<0).^3 *(-1);
plot (p1); grid on; hold on;
plot (v2);
