Online app which plots F(z) in the complex plane

Click For Summary

Discussion Overview

The discussion revolves around the search for an online application that can plot the function f(z) in the complex plane in real-time as the user interacts with it. The focus is on the visualization of complex functions, particularly in relation to the Riemann zeta function and its zeros.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant expresses a need for an app that can plot f(z) instantaneously as the user moves the mouse in the complex plane, highlighting a potential application in visualizing the zeros of the Riemann zeta function.
  • Another participant mentions using Desmos but is uncertain about its capability to handle complex values, suggesting an alternative tool found online.
  • A later reply points out that the graph of a complex function requires four dimensions (two for input and two for output), indicating a challenge in finding suitable applications.
  • One participant clarifies their need for a 2D space where clicking on the plane would plot f(z) immediately, emphasizing the desire for continuous curves if the function is analytic.

Areas of Agreement / Disagreement

Participants do not reach a consensus on a specific application that meets the requirements outlined. There are differing views on the dimensionality needed for plotting complex functions and the capabilities of suggested tools.

Contextual Notes

There are limitations regarding the assumptions about the dimensionality of complex function graphs and the specific functionalities of the suggested applications, which remain unresolved.

I am looking for an app that can instantaneously plot the function f(z) in the complex plane once z is given.
It would be much favorable if this process is fast which allows one to visualize f(z) when the user is moving the mouse on the complex plane to the location of z.
One possible application, is to visualize the zeros of the Riemann zeta function if one move the mouse on the critical line.

My goto one is desmos but I’m not sure if it will handle complex values.

I found this one though

I took a look at this, but it doesn't seem to be what the OP needs. The graph of a complex function ##f : \mathbb C \to \mathbb C## requires four dimensions: two for the complex input and two more for the complex output. I don't have any good suggestions, though.

I just need a 2D space, so that when I click any where in this plane (z), the app immediately plots the f(z) on the same plane. This should also draw f(z) as a continuous curve if the function is analytic.
