Derivative of complex numbers
WebSep 15, 2015 · The derivative should be given by: f' = du/dx + i dv/dx = dv/dy - i du/dy where 'd' is the derivative operator. I've tried the following code: stepx = 0.01; stepy = 0.01; Nx = 2/stepx +1; Ny = 2/stepy +1; [re,im] = meshgrid ( [-1:stepx:1], [-1:stepy:1]); cplx = re + 1i*im; z = cplx.^3; The derivative should be given by: WebChapter 13: Complex Numbers Sections 13.3 & 13.4 Chapter 13: Complex Numbers.
