"rror using matlab.ui.control.internal.model.AbstractNumericComponent/set.Value (line 111)

'Value' must be a double scalar."

I am getting this error message when ever i try running the code. This message after i wrote the last two lines of code, what could it be

Code

% OUTPUT

EqualSums=(SlipAmount/2)+((person1+person2)/2);

SUMPERSON1=EqualSums-Person2Debts;

SUMPERSON2=EqualSums-Person1Debts;

app.DEBTSEditField.Value=SUMPERSON1;

app.DEBTSEditField_2.Value=SUMPERSON2;

same problem ORZ have you solved yet?

[Walter Roberson]

What is class() of SUMPERSON1 and 2? What are size() of them?

Answer 1

[Cris LaPierre]

One of two possible causes.

1. SUMPERSON2 is not a double (see this question for an example)
2. SUMPERSON2 is not a scalar. This error is returned if you try to assign a vector of numbers (e.g. [2, 6]);

You can duplicate the error by running the following in MATLAB.

fig = uifigure;
edt = uieditfield(fig,'numeric');
edt.Value = [5 6];

Error using matlab.ui.control.internal.model.AbstractNumericComponent/set.Value (line 111)
'Value' must be a double scalar.

The solution is to make sure SUMPERSON2 is a single numeric value.

edt.Value = 5;
