Question: Computation time and assigning issues

Hello,

 

I am trying to solve 9 non linear equations in 3 do loops(program attached without loop) and I am using digits:=20; for computing 10 values its takes around 5 minutes. I need to compute around 18000 such values for a plot. It might take several days for this. Is there any mistake in my code which is taking it so long to run or is it just the complexity of the equations.

 

Secondly, I am trying to compute some calculations to the results and assign it to array2 but everytime it shows me some error.

 

Any help is very much appreciated.

Thanks

Vivek
