Using matshow to efficiently show seqeuences of images


I’m using matshow to display a sequence of images in a
QT window; i.e each time a key is pressed a new image is displayed. The
performance seems somewhat sluggish (my baseline here is displaying the images
using opencv). So I’m wondering if there are some well established methods
for using matshow efficiently that I’m missing. Currently, I’m clearing
the figure in between each call to matshow. Does this lead to expensive
deallocation and reallocation of memory which could potentially be avoided by
simply changing the values stored in memory?
