Description of problem
While i was executing the below code
start_scope()
tau = 10ms
eqs = ‘’’
dv/dt = (sin(2pi100Hz*t)-v)/tau : 1
‘’’
Change to Euler method because exact integrator doesn’t work here
G = NeuronGroup(1, eqs, method=‘euler’)
M = StateMonitor(G, ‘v’, record=0)
G.v = 5 # initial value
run(60*ms)
plot(M.t/ms, M.v[0])
xlabel(‘Time (ms)’)
ylabel(‘v’);
BELOW IS THE ERROR
NotImplementedError Traceback (most recent call last)
