在Python中实现一个简单的向量计算器功能,你可以使用内置的数据结构`list`来存储向量元素,并编写一些基本的数学操作函数,比如加法、减法、点积等。下面是一个基础的例子:
```python
class VectorCalculator:
def __init__(self, vector1, vector2):
self.vector1 = [float(x) for x in vector1]
self.vector2 = [float(x) for x in vector2]
# 向量加法
def add(self):
return [a + b for a, b in zip(self.vector1, self.vector2)]
# 向量减法
def subtract(self):
return [a - b for a, b in zip(self.vector1, self.vector2)]
# 点积(内积)
def dot_product(self):
return sum(a * b for a, b in zip(self.vector1, self.vector2))
# 标量乘法(将一个标量乘到每个元素上)
def scalar_multiply(self, scalar):
return [scalar * a for a in self.vector1]
# 使用示例
vector_calculator = VectorCalculator([1, 2, 3], [4, 5, 6])
print("加法结果:", vector_calculator.add())
print("减法结果:", vector_calculator.subtract())
print("点积结果:", vector_calculator.dot_product())
print("标量乘法结果(2倍):", vector_calculator.scalar_multiply(2))
```
