Hi Rene,
Thanks a million for your reply. I am very new to Mathematica, also I have never used any other maths software like Matlab before.
Would you mind to write down some relevant codes for this calculation?
I will write down the steps that I don't know how to code. It will be greatly appreciated if you can provide any help.
-----Let's suppose that there is a function, R(x), with variable x, and R(x)= ? P(x,t) dt. P(x,t) is a function of x and t-----
How to define P as a function of x and t? Will mathematica be able to compute this integral given a small region like {t, t+0.1)
----- Make a "sufficiently dense" () grid of points {x0, y0} in the (x,y}-plane----*
How to define a grid? Can you show me the code for it? Will the grid in Mathematica be able to store an equation?
When I successfully calculate the integral for each interval, {t, t+0.1}, how do I sum it to get R(x)? I may have a million equations stored in the grid and the sum of them, which gives me R(x), will be horrendous.
Thanks again for any help if you can provide!!
Best regards,
Stven
