对任意mn实施基本的Gram-Schmidt分解 矩阵。确保对照提供的测试测试算法 案件。您可以假设m 10和n m(请参阅下一节 细节)。
我已经尝试了上面的方法,但是出了点问题,我需要对其进行另一种实现。
# This variable will keep track of the validity of our input.
inputStatus = True
vector = [1, 0, 1]
def twoNorm(vector):
# This for loop will check each element of the vector to see if it's a number.
for i in range(len(vector)):
if ((type(vector[i]) != int) and (type(vector[i]) != float) and (type(vector[i]) != complex)):
inputStatus = False
print("Invalid Input")
# If the input is valid the function continues to compute the 2-norm
if inputStatus == True:
result = 0
for i in range(len(vector)):
result = result + (vector[i]**2)
result = result**(1/2)
return result
print(twoNorm(vector))
def QR(matrix):
if len(matrix[0]) != len(vector):
print('Invalid')
else:
for i in vector:
q[i] = []
r[i][i] = twoNorm(vector)
q[i].append(i * (1/(r[i][i])))
return q[i]
matrix = [[1, 3], [4, 1], [2, 0]]
print(QR(matrix))
为什么会出现错误?
