how to ds mapping

Hi, basically i'm trying to write a code to compare the values that i have on a table with a certain range and give it a value

if Accel >= 0.28 & Accel < 2.1 this is equal to number 1

if Accel >= 2.11 & Accel < 3.63 is equal to number 2

and then with both values use it to create a map.

Hello @Joao Vital,

To effectively compare values in your table with specified ranges and assign corresponding values, you can leverage MATLAB's logical indexing capabilities.Here are the steps you can follow to acheive this:

• If your data is in a table, you can load it using the 'readtable' function or create it manually. For a better understanding of the 'readtable' function, you can refer to the following documentation: https://www.mathworks.com/help/matlab/ref/readtable.html
• Once the data is loaded, apply logical conditions to compare the 'Accel' values against your specified ranges. Here is a snippet of code for better understanding:

data.AccelValue(data.Accel >= 0.28 & data.Accel < 2.1) = 1;
data.AccelValue(data.Accel >= 2.11 & data.Accel < 3.63) = 2;

• Use the values to create a map. For MATLAB R2022b and previous releases, you can refer to the following documetation: https://www.mathworks.com/help//releases/R2022b/matlab/matlab_prog/overview-of-the-map-data-structure.html

I hope this explanation helps you implement your solution smoothly.
