(R2018a), MATLAB used aseparatestorage representation. The real and the imaginary parts of the numbers were stored separately. MATLAB uses aninterleavedstorage representation for C and Fortran language MEX files, where the real and imaginary parts are stored together.Interleaved complexrefers to this...
Once you have created a complex number, you can use the built-in functions real and imag to extract the real and imaginary parts, respectively. For example, to extract the real part of the complex number z, you would use the following code: a = real(z)。 And to extract the imaginary...

plot(x,real(y),'b');hold on plot(x,imag(y),'r');hold off 也可以画出函数的实部-虚部图：x=-1:0.01:1;y=1.6*cos(2*pi*x)+i*0.4*sin(2*pi*x);plot(y,'b')用polar函数的话可以画出函数的极坐标图。参考资料：http://www.ilovematlab.cn/thread-101480-1-1.html ...
Complex numbers have both real and imaginary parts, where the imaginary unit is the square root of -1. sqrt(-1) To represent the imaginary part of complex numbers, use eitheriorj. c=[3+4i,4+3j;-i,10j] Indexing Every variable in MATLAB is an array that can hold many numbers. When...
The data is stored as a vector of interleaved, double-precision numbers where the real and imaginary parts are stored next to each other. The pointer to this data is referred to as pa (pointer to array). To test for a noncomplex matrix, call mxIsComplex. Before MATLAB Version 9.4 (R20...
