I am trying to call a script (say script2) within another script (say script1). But I have to declare a few variables in script1 before calling script2. When I try to do this, the script1 directly goes to calling script2, without declaring the variables in between. How to overcome this?
{clear
xq=2; yq=2;
script2}

@Sanjit: Please do not invent an own syntax containing curly braces to explain code in the forum. Prefer standard Matlab syntax, because this is understood here in general.

@Jan Simon: Sorry about that. Since this is my first question here, I didn't know about it. I will make sure about this from my next post.
Thank You

You can call one script from inside another without any problems:
% Script 1:
disp('I am script 1')
clear
a = 1;
b = 2;
Script2;
disp('Back in script 1')
disp(a)
disp(c)
And the second script:
% Script2
disp('I am script 2')
c = a + b
When you observe something like "script1 directly goes to calling script2, without declaring the variables in between", there must be another problem. Either you have not saved the script, or you run another script than you think you do. Use the debugger to find out the details: Set a breakpoint in the first line of the script and step through the code line by line.
If the 2nd script contains a clear, all formerly declared variables are deleted. It is a good prgramming pratice to avoid scritps and use functions instead. This allows to control the input and output of variables accurately and without any side-effects. Then the clear command can be omitted completely.

Hey, thank you very much for your answer. Whatever you pointed out in the last paragraph of your answer was exactly what was happening. Once again thank you for such a detailed answer.

You should get rid of the "clear" statements in your scripts.

Hey, that really helped. I was using a "clear" statement in the beginning of the script2, which is getting rid of the already declared variables in the script1. Thank you for pointing it out.
Now my question sounds very silly to me..
