Thank you very much for your help it works that way.
Now i am further trying to improve my calculations by integrating separate calculations i do but ihave no clue how to begin with.
If you look at the 2 files , you could see me calculating the variables k1,k2,h1,h2...etc in file 1 which are in turn used as inputs in file 2 and then the system of equation is solved.
But the problem i have is all my variables calculated in file 1 are function of t , so each time i enter a new t and find the variables for different values of t and then i use them as inputs in file 2.
ex:file 2 has k1vals:=[a b c d] - these four values are calculated by entering different values of t in file 1.
Is there any way to simplify this procedure so i cud do it like a program, where i enter the range of t values like t:[100..500] and then it automatically calculates the variables and uses them as inputs while solving the system of equations ?
I know it sounds confusing but i would be glad to explain in detail what i want to do.
