Hello,

I initialized a matrix as a global variable (in the properties of the app) and I am now trying to fill it thanks to function called in differents callbacks. Is it possible to keep in memory the matrix filled with a previous callback and use it later with another callback.

I don't know if it is possible to create a variable in the properties that keep in memory the matrix filled, and then call it in another part of my code?

Thank you

在 MATLAB Online 中打开

Yes, you can use one matrix for several callbacks and it will keep its values. It will be stored as app property, so you need to use app. .

%in the property section:
mymatrix
%in your callback
app.mymatrix

If the property is private you can only use the matrix in callbacks of appdesigner.

If it is public you can also pass it to functions outside of appdesigner.
