App Designer Error using matlab.ui.​control.in​ternal.mod​el.Abstrac​tNumericCo​mponent/se​t.Value (line 111) 'Value' must be a double scalar.

Hello! I just want to ask how to fix the error shown in the title. My goal is to calculate the margin gains (Gm, Pm, Wcg, Wcp) and show the results in their respective fields that I used in the GUI for App Designer. Here is the code.

I have used an Edit Field (Numeric) for the GUI for the calculated results for Gm, Pm, Wcg, and Wcp

Thank you in Advance

In that line of code, you are converting the value of Gm to a string and then assigning the string to the Value property of your numeric editField.

The error is telling you the value must be a double, not a string.

The solution is to remove string() from any assignment to a numeric edit field..

app.GmEditField.Value = Gm;
