WebNov 2, 2024 · For example, the E fields are (751*751) dimensional matrices in Matlab. How can I calculate curl of E or divergence of E in this case? I mean, if my E fields were just analytical functions of x and y, I could use the in built curl or divergence command of Matlab. But in this case the fields have numerical values at different x,y points. WebDec 15, 2015 · You can determine whether a vector field can be written as the curl of another vector field (in ) by looking at it's divergence. Assume a vector field F can be written as the curl of another vector field, call it G. Then F = curl G. Take the divergence of F, and say div F ≠ 0.
