Matlab App Table Lookup and Interpolation Functionality

7 views (last 30 days)
I am developing a Matlab app and need assistance creating one specific feature. My objective is to implement a table lookup function, enabling users to enter data directly into the app before receiving results from a pre-set table. In cases when there are discrepancies between data entered and table values, interpolation may also be necessary.
Idealy, I would like to work with someone who will not only develop this feature for me but also guide me through its development, explaining code and steps involved, so that I may be able to maintain it myself in the future.

Hi Al-bara kaki,
I understand, you want to develop a MATLAB app which will consist of a table look up function, enabling users to enter data directly into the app before receiving results from a pre-set table.
To achieve these functionalities, you can use these functions,
  • Table
Code example:
myTable = table(x, y, z);
% This creates a table with three columns, x, y, and z.
  • Uicontrol
Code example:
userInput = uicontrol('style','edit','position',[10 10 300 20]);
% This creates a text box at position (10, 10) with a width of 300 pixels and a height of 20 pixels.
  • Interp1
Code example:
inputData = str2double(userInput.String);
tableValue = interp1(x, y, inputData);
% This code reads the input data from the user input field, converts it to a numerical value, and performs a table lookup using the interp1 function. The x and y vectors are the first and second columns of your table, respectively. The inputData value is used as the lookup point.
  • Uitable
Code example:
resultTable = uitable('Data',[inputData tableValue],'Position',[10 40 300 80]);
% This creates a table with the input data and the corresponding table value. The table is positioned at (10, 40) with a width of 300 pixels and a height of 80 pixels.
Kindly refer to the following links to learn more about these functions,
I hope this helps,
