matlab中imag什么意思,Matlab基本函数-imag函数

1、imag函数：求复数的虚部部分

2、用法说明

Y=imag(X) 函数计算复数X的虚数部分Y。输出结果Y与输入X的维数相同，返回值为复数数组X中的每个复数的虚部

3、举例说明

>> x = [1.2+2.3i 4+5.3i 34-123.456i 78-123456.78967i]

x =

1.0e+05 *

0.0000 + 0.0000i 0.0000 + 0.0001i 0.0003 - 0.0012i 0.0008 - 1.2346i

>> y = imag(x)

y =

1.0e+05 *

0.0000 0.0001 -0.0012 -1.2346
