Hey!
I have stored a number of images in a cell that I have to access in app-designer.
I want to use the slider (and its value) to decide what picture I want to show, but I cant access it. It says:
"Brace indexing is not supported for variables of this type"
function PlotImages(app)
imshow(app.subImage,'Parent',app.AxChosenCell);
end
function Slide(app)
app.subImage = round(app.SliderChosenCell.Value);
app.subImage = app.subImage{app.SliderChosenCell.Value};
end
I have a 6x1 cell (containing 6 images (n x m))

What the error message means is that you cannot use {} to index your app.subImage because for that type of variable, {} indexing has no meaning. It looks like your code is expecting app.subImage to be a cell array. It is not. You'll have to see what round(app.SliderChosenCell.Value) is returning and use proper indexing.

What ever app.subImage was before, after:
app.subImage = round(app.SliderChosenCell.Value);
it is a scalar number with an integer value. Then:
app.subImage = app.subImage{app.SliderChosenCell.Value};
cannot work.
"I have a 6x1 cell (containing 6 images (n x m))" - this is not clear. Which variable contained this cell array?
