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.

Witryna6 lut 2015 · Next we use the forward difference operator to estimate the first term in the diffusion equation: The second term is expressed using the estimation of the second order partial derivative: Now the diffusion equation can be written as. This is equivalent to: The expression is called the diffusion number, denoted here with s: 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…
