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? Thank you for your answers.

What does this show, after you get x and a:

whos x
x
whos a

When I write to prompt 2 (number of figure). Comand Window returns this:

x = 
      '2'
a =
2
Zadali jste správné číslo.
x = 
       {}
Index exceeds matrix dimensions.

can you upload the mat file, and change the prompts to English and I'll try to run your exact code?

file.m

Ok, there is m.file. I work with EIDORS, but I deal with vector and cell.
