Dear all,
I have variable xx and cell (velky). I want to choose one vector velky {2,a} (for example velky{2,1})of this cell and assigned to a variable xx. I try to do this, but withnout succes.
This is my code:
load ('testovaci_modely_velke_skvrny')
load ('net')
prompt = {'Napište číslo testovacího modelu:','z'};
dlg_title = 'Vytvoření vlastního testovacího modelu';
num_lines = 1;
x = inputdlg('Napište číslo testovacího modelu:','Vytvoření vlastního testovacího modelu', [1 100]);
a = x{1,1};
disp('Zadali jste správné číslo.')
xx = velky{2,a};
% Y = sim(net,P);
imdl= mk_common_model('a2c0',16);
img_1 = mk_image(imdl);
img_input = img_1;
img_input.elem_data = xx;
figure
show_fem(img_input);
title('Testovací model')
Does anyone have any idea? I work with EIDORS, but in this case it is about vector and cell. Thank you for your answers.
I attach my matfile,testovaci_modely_velke_skvrny and net.

Please try to include information on any errors with questions like this. Just saying "without success" doesn't really make it easy for us to help quickly.
Looking at your code and running what seems relevant I think the problem is that
a = x{1,1};
is giving you a string as answer because it is taken from an input dialog. You need to convert the string to a number.
Try replacing that with:
a = str2double( x{1,1} );
then your syntax
xx = velky{2,a};
which is correct should work fine.
