I have non-image data that I would like to convert to images for use in CNN. Any help would be appreciated.

Of course you can view the images but they will be very small so you need to magnify them to see them.
imshow(thisImage, [], 'InitialMagnification', 3000);
Remember images must be rectangular. 3 is not for gray scale. So since you have 21 elements, you can either have a 3x7 or a 7x3 image. So you don'[t really have much choice. 3*7 = 21 and 7*3 = 21. No other combinations multiply to give you 21. Or you can have a different size if you want if you paste it in to the upper left corner.
Remember some predefined networks require images of a certain size so you may have to use imresize() with the 'nearest' option if you want to use a prebuilt network such as AlexNet. Or you can build your own, which might train faster since your images will be so much smaller than those used for prebuilt networks, such as 227x227 for Alexnet.

You can use an arrayDatastore after reading in the files, or perhaps a tabularTextDatastore . You probably do not need to convert to images.
