Logarithmic transformations have two pairs of logarithmic coordinate transformations and single-axis logarithmic transformations. Double logarithmic coordinate conversion can be realized by loglog function, and single-axis logarithmic coordinate conversion can be realized by semilogx and semilogy function.
Loglog(Y) means that the x and y coordinates are both logarithmic coordinates.
Semilogx(Y) indicates that the x coordinate axis is a logarithmic coordinate system
Semilogy(...) indicates that the y coordinate axis is a logarithmic coordinate system
Plotyy has two y axes, one on the left and one on the right
Example 1: Create a simple loglog with square markers.
Solution: Enter the command
x=logspace(-1,2);
Loglog(x,exp(x),'-s')

Example 2: Create a simple semi-logarithmic graph.
Solution Enter the command:
x=0:.1:10;
Semilogy(x,10.^x)

The 7-inch tablet can be used as the golden size of a tablet computer. It is small and portable. It can be used at home and outdoors. You can browse the web, watch videos and play games. It is a household artifact. Although the size of the 7-inch tablet is inclined to the tablet, the function is more inclined to the mobile phone, so it can also be used as a substitute for the mobile phone. Compared with other sized tablets, the 7-inch tablet has obvious advantages in appearance and weight. Both the body size and the body weight have reached a very reasonable amount.
1.In appearance, the 7 inch tablet computer looks like a large-screen mobile phone, or more like a separate LCD screen.
2.In terms of hardware configuration, the 7 inch tablet computer has all the hardware devices of a traditional computer, and has its own unique operating system, compatible with a variety of applications, and has a complete set of computer functions.
3.The 7 inch tablet computer is a miniaturized computer. Compared with traditional desktop computers, tablet computers are mobile and flexible. Compared with Laptops, tablets are smaller and more portable
4.The 7 inch tablet is a digital notebook with digital ink function. In daily use, you can use the tablet computer like an ordinary notebook, take notes anytime and anywhere, and leave your own notes in electronic texts and documents.
