How to call a variable from one program to another program 2 in app designer?

The problem I have is that in a first program I calculate variables "a" "b" "c" "d" etc.

I want to call these variables to a second program to use them in other equations.

In the first program I have a button that opens the second program.

When running I get the following error.

Error using /

Matrix dimensions must agree.

Error in app2Class/startupFcn (line 42)

app.Tabla1.Data{1, 2} = (24/a )+(3/(a ^0.5))+0.34;

Error in matlab.apps.AppBase/runStartupFcn (line 68)

ams.runStartupFcn(app, startfcn);

Error in app2Class (line 103)

runStartupFcn(app, @startupFcn)

Error in app1/Paso2ButtonPushed (line 438)

app2Class

Error in matlab.apps.AppBase>@(source,event)executeCallback(ams,app,callback,requiresEventData,event) (line 62)

newCallback = @(source, event)executeCallback(ams, ...

Error while evaluating Button PrivateButtonPushedFcn.

I want to clarify that "a" was already calculated.

Thanks for your help.

I am guessing that you actually require element-wise division, not matrix division:

If you want to use MATLAB then you need to learn the difference between array operations and matrix operations.

app.Tabla1.Data{1, 2} = (24./a )+(3./sqrt(a))+0.34;
