Error using plot
Vectors must be the same length.
Error in Well16_1_A_06 (line 263)
plot(Out(:,1),regtime,'k');
While the length of remtime is 926 and length(Out) = 765

We can't really answer that for you, because we need more information.
Suppose
x = [1 2 3 4];
y = [5 6 2 3];
If I want to plot x vs. y, we have a clear one-to-one correspondence between each (x,y) pair. MATLAB knows what to plot.
But now suppose
x = [1 2 3 4 5 6 7];
y = [5 6 2 3];
Now, it is not clear how to plot x vs. y. How do we make the correspondence between x and y? We need more information.
Similarly, for your problem, we don't know how to make the correspondence between your 926 values and your 765 values, without more information.
