I have systems: function HR!(du, u, p, t) function sigma(x) return 1.0 / ( 1.0 + exp( -10.0 * ( x - ( - 0.25 ) ) ) ) end a, b, c, d, s, xr, r, I, vs, k1, k2, el_link = p x1, y1, z1, x2, y2, z2 = u du[1] = y1 + b * x1 ^ 2 - a * x1 ^3 - z1 + I - k1 * …

The incorrect use of SVectors does exist here, but since the return is unused it just gets deleted by the compiler so that’s fine. Here’s a break down: using OrdinaryDiffEq function sigma(x) return 1.0 / ( 1.0 + exp( -10.0 * ( x - ( - 0.25 ) ) ) ) end function HR!(du, u, p, t) a…
