Error in following codes
for i = 1:12
if i == 12
x1 = 9
end
x1 = [1];
x2 = [3];
if i == 1
x1 = 2
else
x1(i) = x1(i-1) - x2;
end
x = [x1 x2]
end
When i run it it shows following error please help me to solve error.
Array indices must be positive integers or logical values.

Yes, but did Star's answer below solve your problem or not? Did you even try it?

The error comes from your current calculation of ‘x1’ as:
x1(i) = x1(i-1) - x2;
In the first iteration,i=1 so (i-1)=0. In MATLAB, indices are integers greater than 0, or logical values.
I am not certain this ‘corrected’ version of your code creates the values for ‘x’ that you want. However, it has the virtue of running without error:
for i = 1:12
if i == 12
x1(i) = 9;
end
x1(i) = [1];
x2 = [3];
if i == 1
x1(i) = 2;
else
x1(i+1) = x1(i) - x2;
end
x(i,:) = [x1(i) x2];
end
Experiment to get the result you want.
