Displaying images from cell arrays in app designer

Question

I have a cell array whose cells contains images and I am trying to individually display the images in app designer.

I have tried the following code in app designer:

    cellarray = uigetfile('*.*;');
             Z = {cellarray,1};
             c = imread(Z);
             imshow(c,'Parent',app.UIAxes)

Here, I save a cell array as a .mat file which I try to open in an app.

However, it says that brace indexing is not supported.

I'm confused as the indexing in line 2 of the code above would work in the baseline MATLAB workspace but it doesn't seem to work in app designer?

Thanks for your help.

It looks like you are indexing your cell array incorrectly. See this page: Access Data in Cell Array.

Try something like this (untested)

cellarray = uigetfile('*.*');
Z = cellarray{1};
c = imread(Z);
imshow(c,'Parent',app.UIAxes)
