两种生成矩阵的方法：
先生成列表，再生成矩阵。

def ReadTxtName2(rootdir):   # 按行读取txt，生成列表
    lines = []
    with open(rootdir, 'r') as file_to_read:
        while True:
            line = file_to_read.readline()
            if not line:
                break
            line = line.strip()    #去掉每行头尾空白 
            line = line.strip('\n')  #去掉最后的换行符
            if line:
                s = line.split(' ')   #每行元素间用空格做分割
                a = []
                for i in range(0, len(s)):
                    a.append(int(s[i]))
                lines.append(a)
    return lines

if __name__ == '__main__':
    resultpath = r'新建文本文档.txt'
    c = ReadTxtName2(resultpath)
    print("c = ",c ,type(c))

   # 生成矩阵
   #方法1：
    for i in range(0,len(c)):
        c[i] = np.array(c[i])
    d1 = np.array(c)
    print("d1 = ",d1 ,type(d1))
    #方法二：
    d2 = np.matrix(c)
    print("d2 = ",d2 ,type(d2))
