numpy.multiply: 对两个数组的对应元素进行乘法运算。 numpy.divide: 对两个数组的对应元素进行除法运算。 numpy.sin: 计算数组中每个元素的正弦值。 numpy.cos: 计算数组中每个元素的余弦值。 numpy.log: 计算数组中每个元素的自然对数(以e为底的对数)。
However, minimize() finds the minimum value of a function, so you’ll need to multiply your objective function by -1 to find the x-values that produce the largest negative number. There is one constraint on the problem, which is that the sum of the total shares purchased by the buyers ...
