print(x.real): Prints the real part of the square root of the complex number (1+0j) stored in ‘x’. print(y.real): Prints the real part of the square root of the complex number (0+1j) stored in ‘y’. print(x.imag): Prints the imaginary part of the square root of the com...
顺便提及,j部分是复数的虚数系数。 但是,您可以将浮点数转换为复数,例如complex(1.0)。 复数的实部和虚部可以分别通过real()和imag()函数提取。 数据类型对象 数据类型对象是numpy.dtype类的实例。 数组再次具有数据类型。 确切地说,NumPy 数组中的每个元素都具有相同的数据类型。 数据类型对象可以告诉您数据的大小(...

An array of the same type asa, containing the rounded values. Unlessoutwas specified, a new array is created. A reference to the result is returned. The real and imaginary parts of complex numbers are rounded separately. The result of rounding a float is a float. ...
Chapter 1 of NumPy Beginners Guide. This program demonstrates vector addition the Python way. Run from the command line as follows python vectorsum.py n where n is an integer that specifies the size of the vectors. The first vector to be added contains the squares of 0 up to n. ...
· real: 代表一个array中所有元素的实数部分 · imag: 同理,代表一个array中所有元素的虚数部分 · flat: 将这个array整理成一维的,可以索引的一系列的元素组合。它实际上是通过iterator实现的,我们可以通过for x in array.flat来取得到所有的元素
For complex `X`, the legal options for `fmt` are: * a single specifier, `fmt='%.4e'`, resulting in numbers formatted like `' (%s+%sj)' % (fmt, fmt)` * a full string specifying every real and imaginary part, e.g. `' %.4e %+.4ej %.4e %+.4ej %.4e %+.4ej'` for 3...
