求矩陣中向量兩兩間的歐氏距離(python實現)

假設有兩個三維向量集，用矩陣表示:

要求A，B兩個集合中的元素兩兩間歐氏距離。

先求出ABT：

然後對A和BT分別求其中每個向量的模平方，並擴充套件為2*3矩陣：

然後：

將上面這個矩陣一開平方，就得到了A，B向量集兩兩間的歐式距離了。

程式碼:

def EuclideanDistances(A, B):
    BT = B.transpose()
    # vecProd = A * BT
    vecProd = np.dot(A,BT)
    # print(vecProd)
    SqA =  A**2
    # print(SqA)
    sumSqA = np.matrix(np.sum(SqA, axis=1))
    sumSqAEx = np.tile(sumSqA.transpose(), (1, vecProd.shape[1]))
    # print(sumSqAEx)

    SqB = B**2
    sumSqB = np.sum(SqB, axis=1)
    sumSqBEx = np.tile(sumSqB, (vecProd.shape[0], 1))    
    SqED = sumSqBEx + sumSqAEx - 2*vecProd
    SqED[SqED<0]=0.0   
    ED = np.sqrt(SqED)
    return ED
