The end operator must be used within an array index expression.

Hi,

I am reading every 600th frame from the video by using the end operator but I am getting this error here.

Code:

v = VideoReader('DSC_1191.MOV');

frame = read(v,[600:600:end]);

Error:

The end operator must be used within an array index expression.

Error in Spec_Frame (line 3)

frame = read(v,[600:600:end]);

See the original question - i fixed the error.

frame = read(v,[600:600:end]);

will not work in this case.

In this case read is a function, not a variable. Attempting to "index" into the function with end won't work. I would probably replace end with v.NumFrames.

Thank you for the clarification.
