SUMMARY

This discussion focuses on using the surf() function in MATLAB for 3D plotting of router power readings in dBm across a square space. The user seeks guidance on how to properly arrange matrices for effective visualization. Key points include the necessity of structuring the data into appropriate X, Y, and Z matrices to represent the spatial distribution of power readings accurately. Participants emphasize the importance of providing specific matrix examples to facilitate targeted assistance.

PREREQUISITES
  • Understanding of MATLAB programming environment
  • Familiarity with 3D plotting concepts
  • Knowledge of matrix manipulation in MATLAB
  • Basic understanding of signal strength measurements in dBm
NEXT STEPS
  • Research how to create mesh grids in MATLAB using meshgrid()
  • Learn about data visualization techniques in MATLAB, specifically for 3D plots
  • Explore MATLAB documentation on the surf() function for advanced features
  • Investigate examples of 3D plotting with real-world data to understand matrix arrangements
USEFUL FOR

This discussion is beneficial for MATLAB users, data analysts, and network engineers who need to visualize spatial data, particularly in the context of signal strength and power distribution analysis.

Hello,

i have a function that i need to plot in 3d, it specifically describes the change in the power of a router considering many readings in different places..

so i have the power in dBm against a square space of a building..

if anyone can help me use the surf(), how should i arrange the matrices??

Welcome to PF!

What have you tried so far? What does your matrix (or matrices) look like? Please provide some of these details so that we can help you in ways other than saying "Check the documentation".
