SVG has two sets of Coordinate Systems: Window coordinate system and user coordinate system. By default, the points in the user coordinate system and the window coordinate system correspond one by one. Let's take a look at the coordinates and

One day, I tried to search the calculator and found that it was JavaScript, and I had to click it one by one, but it could not be recorded. it was easy to make mistakes when I entered the formula, so I thought about how to make it easy to use. I can

Zeros (2, 3) is initialized as a 2*3 matrix. Eye (3) initializes a 3*3 square matrix with a diagonal element of 1. Linspace (, 5) generates numbers from 2 to 4, which is an arithmetic difference series. When we add 2 and 4, there will be 5 numbers,
