SciPy的 - 如何使基質與特定的行和列

Question

我有以下代碼：

import scipy as sc 
import matplotlib.pyplot as plt 
.... 
MeanSquareDistance1D=lambda n,m: ((m*Lastpoint1d(n)**2).sum())/m 
...... 

data=[] 
for i in range(10,110,20): 
    #mydata=list(sc.mat([[i],[MeanSquareDistance1D(i,2000)]])) 
    #data.append(mydata) 

    mydata=(sc.array([i,MeanSquareDistance1D(i,2000)])).tolist() I did it like this 
    data.append(mydata) 

plt.plot(data) 
plt.show() 

我想要「MYDATA」是一個矩陣或陣列（優選）（我它convering到列表爲了做圖）與我行（5行）和2列。 第一列應該是'i'，第二列是MeanSquareDistance1D（i，2000）的值。 我收到錯誤「ValueError異常：x和y可以是不大於2-d」

Answer 1

import scipy as sc 
import matplotlib.pyplot as plt 
.... 
MeanSquareDistance1D=lambda n,m: ((m*Lastpoint1d(n)**2).sum())/m 
...... 

data=[] 
for i in range(10,110,20): 
    #mydata=list(sc.mat([[i],[MeanSquareDistance1D(i,2000)]])) 
    #data.append(mydata) 

    mydata=(sc.array([i,MeanSquareDistance1D(i,2000)])).tolist() I did it like this 
    data.append(mydata) 

plt.plot(data) 
plt.show()
