WitrynaAlways look for a way to use an existing numpy method for your application. np.roll () will allow you to shift and then you just add. I learned to use convolve () from comments on How to np.roll () faster?. I haven't checked if this is faster or not, but it may depend on the number of dimensions. The error in a method's solution is defined as the difference between the approximation and the exact analytical solution. The two sources of error in finite difference methods are round-off error, the loss of precision due to computer rounding of decimal quantities, and truncation error or discretization error, the difference between the exact solution of the original differential equa…
