how to change this code to matlab

Halo,

i wanna ask how to convert this source code to matlab, i have difficulty in doing it. can you help me ?

def train_network(network, train, l_rate, n_epoch, n_outputs):
	for epoch in range(n_epoch):
		sum_error = 0
		for row in train:
			outputs = forward_propagate(network, row)
			expected = [0 for i in range(n_outputs)]
			expected[row[-1]] = 1
			sum_error += sum([(expected[i]-outputs[i])**2 for i in range(len(expected))])
			backward_propagate_error(network, expected)
			update_weights(network, row, l_rate)
		print('>epoch=%d, lrate=%.3f, error=%.3f' % (epoch, l_rate, sum_error))
