Combining the above derivation process into two steps, the key features used are also 3.2:Get analysis ResultsSo we get the discrete-period signal Fourier series:PropertiesThe properties of the Fourier series of discrete periodic signals are similar to those in continuous cases and are summarized in the following table in the original book:to add a Paswal theorem:SummaryThe difference between Fourier series and continuous conditions of discrete-time periodic signals is

If you want to disable items in the gridview, you need to do the following two things:
1. areallitemsenabled of override Adapter
2. isenabled (INT position) of override Adapter)
3. If you want to set the items corresponding to the gray object during disable, you only need to set the Alpha value of the corresponding view in the getview method.
For example:
class MyAdapter extends BaseAdapter { @Override public boolean isEnable(int position)

what is the brightness value of a Real-Color Pixel when it is converted to a grayscale image? The average value we first think of is R + G + B/3. In reality, we use the following formula:
Y = 0.299r + 0.587G + 0.114b
This formula is generally referred to as the grayscale formula of psychology. Here we can see that the green component accounts for the largest proportion. Scientists found that the grayscale image obtained by using the above formula is the closest to the human's perception of the
