I have the following values of the variable V: 20930.4 - 49414.8i, 126492. + 43093.7i are complex values. And there is a sigma value: 2*10^4. How do I plot the Re and Im parts of V against sigma from them in wolfram mathematica? Also I need to do the same thing for kappa, chi.
Have you tried ReImPlot?
You have two complex numbers and a real number. What kind of plot have you in mind?
Plot of Re(V) dependence on sigma, Im(V) on sigma and so on. I don’t know how this plot supposed to look like exactly
Then write a formula for V as a function of sigma.
Maybe you are looking for something like this below?
Thank you, I already done this ReImPlot[{V0,V1},{[Sigma],210^2,210^4}], but it seems that ReImPlot can’t see that there is a dependency between V and sigma in my program, so this function plot horizontal constant lines, but when I’ve inserted whole equation in ReImPlot, like the values for theta, Y, I’ve managed to get plot like yours. How did you do that without inserting whole equations? My guess is that it got something to do with the first line in your code: Remove@Evaluate[Context[]<>“*”], am I right?
No, that is not the case. The Remove@Evaluate[ ... line just comes from my personal typing habits. I have since edited it to be the more common Clear[“`*”].
More to the point is that I commented out the line in your code where sigma is assigned a value. Which made it act as a constant:
OK, otherwise, thank you!
