"Vectors must be same length" Please help with plotting!

I'm trying to plot the following and it will not allow me to, because apparently the vectors are not the same length. What am I missing?

h = [0:1:11];
for i = 1:length(h);
    T(i) = To - (6*h(i));
end
plot(h,T)

Is T defined anywhere previously in the code?

Note that the square brackets are superfluous:

You possibly do not need a loop, just use this:

h = 0:11;
T = To - 6*h;

Hi,

What is the value of 'To'?

Is 'To' a scalar o vector?

The following code has not errors:

To = 0;
h = [0:1:11];
for i = 1:length(h);
    T(i) = To - (6*h(i));
end
plot(h,T)
