Matplotlib is a 2D drawing library on Python that can produce many high-quality images on top of the platform. The aim is to make simple things easier and make complex things possible. We can use Matplotlib to generate plots, histograms, power spectra, histogram, error plots, scatter plots, and so on. Matplotlib was invented by John Hunter (1968-2012), and unfort

Problem DescriptionThe Geosurvcomp Geologic Survey company are responsible for detecting underground oil deposits. Geosurvcomp works with one large rectangular region of land at a time, and creates a grid that divides the land into Numer OUs square plots. It then analyzes each plot separately, using a sensing equipment to determine whether or not of the plot contains oil. A plot containing oil is called a pocket. If the pockets is adjacent, then they

MATLAB is often used to calculate vector graphs. We hope to express them intuitively and compare them through observation.
Therefore, we hope to draw a vector chart.
MATLAB provides the vector plot function: quiver ()
MATLAB help provides instructions:

example, when you are a child, you may have used an essay titled "my father". The purpose is to let the readers know that the essay describes the story of your father.
People, things, and places: an article will naturally involve people, things, and places where things happen. For example, in my father's article, there is usually a classic story: I remember when I was a child, I had a high fever and heavy rain at night, and I couldn't get a car. My father ran to the hospital with heavy rain. T

5. Obtain the GID value of Block 1
6. Determine the GID value of Block 1
7. Add the toll based on the GID level of the No. 1 plot
8. Add the sprite Block 1 to the container.
9. continue to search for the adjacent No. 2 plot on the left. The solution is the same as that of No. 1 plot.
10. If there is no land block on the left, exit the search cycle for the land block on the left and continue searching for the land block on the right.
