Acquire images in loop and save as different name

Hey,

I'm running a for loop where I acquire images from my webcam using snapshot(). Through each iteration of the loop, I'd like to have each image have a different name so I can look at them all at the end, without the previous ones being overwritten.

I do NOT want to save them to the disk, just a different name in the script, and I have no idea how to do this.

Hope you guys can help! :)

Thanks!

Simply put the frames into a cell array:

 C = {};
 for ... % your loop
     C{end+1} = snapshot(...);
 end

And then use indexing to access them. Simple!

Creating new variables dynamically is slow and buggy:

Thanks, thought I had tried that... Was using these [] instead of these{}... stupid mistake

Thanks again! :)

Sometimes it's tricky to figure out when to use braces, parentheses, or brackets. We try to explain it in the FAQ entry on cell arrays: http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F
