Hello, I have a memory Issue.
I am capturing upto 500 images (12 bit tiffs) and storing them in an array.
I preallocate memory:
numImages=500; %Maximum number of images in a stack
global imgArray;
imgArray=cell(numImages,1
Then in another function that captures the images (and adds to an exes component created using GUIDE),
I add to the image array
axes(handles.axes1); cla reset; %Remove any previous graphics on the axes
global imgArray;
imgArray{nextImgIdx}=img;
What I've noticed is at the end once I have finished, I have a seperate function that supposed to clear these images from memory, but looking in task manager, Im still seeing about 3G RAM being taken up from matlab.
%Function to clear memory taken from images
axes(handles.axes1); cla reset; %Remove any previous graphics on the axes
imgArray=[];
