在线Matlab 向量 点积 可以用R语言


x1 = [0.05540125 -0.33735585 -0.2531775 -0.43814594 -0.09458714 1.0648558 -0.5353676 -0.9636384 -0.7925104 0.09754358 -0.10920998 0.00244618 0.03180499 0.04420318 -0.1294798 0.03797745 -0.05250629 -0.5419286 -0.14957885];
y1 = [36 0 5.0000000000 2 4.0 6.57 01 04 01 01 02 06 03 07 15 08 04 1 1];

x=dot(x1,y1)


output=1/(1+exp(-x))
