分别使用C语言和Python实现矩阵归一化

#include <stdio.h>
#include <algorithm>
void mean(float *data,int len,float &mean,float &max,float &min){
float sum=data[0];
max=data[0];
min=data[0];

for (int i = 1; i < len; ++i)
{
sum+=data[i];
if(data[i]>max)max=data[i];
if(data[i]<min)min=data[i];
}
mean=sum/len;
}

void normalize(float *data,int len){
float m=0.0;
float mx=0.0;
float mn=0.0;
mean(data,len,m,mx,mn);
printf("mean:%f\nmax:%f\nmin:%f\n",m,mx,mn );
for (int i = 0; i < len; ++i)
{
data[i]=(data[i]-m)/(mx-mn);
}
}

def Normalize(data):
m = np.mean(data)
mx = max(data)
mn = min(data)
return [(float(i) - m) / (mx - mn) for i in data]
