Matlab multilevel array data removal based on value

I have a 1152x1324x3 uint8 array comprised of RGB values (the interval for all values is [0,255] for each of the three levels). A sample of the data is listed below:

ans(:,:,1) =

    *0*  132  132  140  140  169  169  120  120  126  126
    *0    0    0    0    0*  114  114  147  147  134  134
    *0    0    0    0    0*  114  114  147  147  134  134

ans(:,:,2) =

    *0*  118  118  125  125  161  161  120  120  130  130
    *0    0    0    0    0*  110  110  141  141  128  128
    *0    0    0    0    0*  110  110  141  141  128  128

ans(:,:,3) =

    *0*   94   94  100  100  137  137   73   73   82   82
    *0    0    0    0    0*   79   79   86   86   71   71
    *0    0    0    0    0*   79   79   86   86   71   71

I would like to scan the data and remove all entries in which the value for all three levels is 0. The entries which are bolded (have *s around them) are examples of the entries that I would like removed completely. How would I do this?

Keeping in mind that images must remain rectangular, what does "remove" mean to you? You can't have images with 10 columns in row 1 and 6 columns in rows 2 and 3. There has to be some value there. Why don't you just step back and give us the overall big picture (no pun intended). You can't "remove" pixels, but what do you really want to accomplish? Do you want to find regions of a certain color, or what????

The comment by Image Analyst is correct, every pixel location in an image must have some RGB value, so you cannot remove them per se.

However, to find which (i,j) locations are 0 in all three levels, you can use the MATLAB code below. This will return a logical 1152x1324 matrix in your case with 1's in the locations where the three level values are all 0.
