Below shows a simple structure for what I think you want to do.
function GUI()
fig = uifigure;
p = uipanel(fig,'Position',[20 20 196 135]);
File = uieditfield(p,'Text','Position',[5 60 190 50],'Value','File Name');
btn = uibutton(p,'Position',[5 5 190 50],'Text','Open','ButtonPushedFcn', @ButtonPushed);
function ButtonPushed(~,~)
r=readmatrix(File.Value);%not sure what kind of file you are reading/opening
end
end
