Matlab App Table Lookup and Interpolation Functionality

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.
