Matlab 2D Movie animation

Hi, this is my code:

for strIndex = 1:length(str)
    %Reference to a cell
    name = str{strIndex};
    imagesc(eval(name));
    %Using jet colormap and colorbar
    colormap(jet);
    colorbar;
    axis image;
    axis off;
    newStr = split(name, '_');
    title(newStr{3});
    drawnow;
    %Save each frame into M
    M(strIndex) = getframe(gcf);
end

when I try to run the for loop I keep getting an error that says

"Error in heatmap_display (line 28)

imagesc(eval(name));"

what does this mean and what can I do about it?

We don't know what name is, but I assume a list of image files?

You are not loading the image first. Load it to a variable, then use imagesc to display it.

I don't think it makes sense to use eval here. The steps could be

name = str{strIndex};
im = imread(name);
imagesc(im);
