Previously, I learned about matrices in linear algebra and had some knowledge about the basic operations of matrices. I learned how to use matrices to change images when I used GDI + some time ago, after reading this article, I will summarize it

Matrix learning-Basic Knowledge Previously, I learned about matrices in linear algebra and had some knowledge about the basic operations of matrices. I learned how to use matrices to change images when I used GDI + some time ago, after reading this

In the linear algebra before learning the matrix, there are some understanding of the basic operation of the Matrix, some time ago in the use of GDI + to learn how to use the matrix to change the image, after reading here to summarize the

Recently, I learned about Android Image Processing in the system (I collected some information on the Internet and compiled my own testing program.) Here I will summarize: I. colormatrix class Colormatrix is a 5x4 matrix. The first line indicates

Introduction to the formula of sin function Grammar: SIN (number) Number is the angle, in radians, that requires a sine. Note: If the unit of the parameter is degrees, you can multiply PI ()/180 or use the RADIANS function to convert it to

MATLAB plot The powerful drawing function is one of the characteristics of MATLAB. MATLAB provides a series of drawing functions. You don't need to think too much about drawing details, but you only need to give some basic parameters to obtain the
