Problems of displaying images with matlab

According to your description, provide two methods, the idea is as follows, you try:

1、imshow(I/256)； ? Convert the image matrix to 0- 1?

imshow(I，[])； ? Automatically adjust the range of displayed data?

2. Or consider that the minimum value of I is 0 and the maximum value is 255, which is black and white.

Data expansion:

1, MATLAB, Mathematica and Maple are also called the three major mathematical softwares. It is second to none in numerical calculation in mathematical science and technology application software. MATLAB can perform matrix operations, draw functions and data, realize algorithms, create user interfaces, and connect programs in other programming languages. Mainly used in engineering calculation, control design, signal processing and communication, image processing, signal detection, financial modeling design and analysis and other fields.

2. The basic data unit of 2.MATLAB is matrix, and its instruction expression is very similar to that commonly used in mathematics and engineering. Therefore, it is much simpler to solve problems with MATLAB than to do the same thing with C, FORTRAN and other languages, and MATLAB also absorbs the advantages of Maple and other software, making MATLAB a powerful mathematical software. Support for C, FORTRAN, C++ and JAVA has also been added in the new version.
