Import mat file in to App Designer

hello community, I'm new in app designer and I'd like to ask your support to understand how to process some data.

I got a .mat file that contains data (vectors) each vector has different name:

I created a funtion to load above data to read values from EGSDCmn_mfEgCat1B1Parl_1

properties (Access = public)

var1 = load('C:\Users\T0104G4\Documents\MATLAB\ECT\practise\Data.mat') % Load mat files

end

methods (Access = public)

function results2 = fun1(app)

results2=app.var1.EGSDCmn_mfEgCat1B1Parl_1;

end

end

my target is to push a button to see that data in a app.TextArea

% Button pushed function: LoadDataButton

function LoadDataButtonPushed(app, event)

app.TextArea_2.Value = fun1(app)

but I got this error

any advice/feedback will be highly appreciated.

thanks

Hello A-Rod,

You need to first load the file and store it in a variable.

This Variable must be centrailized such a way that enitre app uses this variable.

for Example:

properties (Access = public)
        var=load('\path_to_location\example.mat'); % specify the path to mat file
end

methods (Access = public)

function results = fun1(app)
    results=app.var.d;
end

You can first start with this sample example.mat

You can create some variables inside the .mat file and try it.

here is the documentation of Matworks for App Designer.
