matrix是array的子集,matrix只能是2维的,array可以是n维的。2维就是matrix的shape只有行、列属性,就类似线性代数中的矩阵;比如说3维的array如同: 下面就来比较array好matrix计算区别: 乘法符号 *:array的乘法符号就是对应元素相乘,比如: 如果行列数不匹配会自动补全,就是numpy的...

目录(?)[+] list array matrix 用python中的numpy包的时候不小心踩了array和matrix的大坑,又引申一下比较list array matrix之间的异同 1、list list可以明显和array、matrix区分,list通过[ ]申明,支持append extend等方法,没有shape方法。 使用如下: data=[] data.append([1,2]... ...
Numpy的矩阵对象与数组对象相似,主要不同之处在于,矩阵对象的计算遵循矩阵数学运算规律。矩阵使用matrix函数创建。 >>> A=matrix('1.0 2.0;3.0 4.0') >>> A matrix([[1., 2.], [3., 4.]]) >>> b=matrix([[1.0,2.0],[3.0,4.0]])
