所以(6ax+2b)+(3ax^2+2bx+c)=2x^2+1 所以3a=2,6a+2b=0,2b+c=1 a=2/3,b=-2,c=4 故特解为Y=2/3x^3-2x^2+4x 原方程对应齐次方程的特征方程为r^2+r=0 r=-1或r=0 所以齐次方程的通解为y*=C1e^(-x)+C2 原方程的通解为y=C1e^(-x)+C2+2/3x^2-2x^2+4x ...
findHomography provided by OpenCV or here you'll find something for Matlab. Both return a homography (3x3 matrix). You can use it to transform further coordinates. OpenCV does this for you with perspectivetransform (is actually a simple matrix multiplication with Homogeneous coordinates, so it's ...

Let’s illustrate this with a practical example. Suppose you have the following 3x3 matrix: # Define a 3x3 matrixx1<-c(10,8,4)x2<-c(7,9,3)x3<-c(11,2,5)# Bind the matrixA<-rbind(x1,x2,x3) Now, let’s use thesolve()function to find the inverse of this matrix: ...
∀u,v, Au=v ⇔ A⁺v=u, would mean that A is invertible and its inverse is A⁺. Which can't be. Since it is a 3×5 matrix. Think of it as information theory. If A⁺A were identity, that would be that if you have 5 numbers to store in a file, you could ...
Many students have difficulty finding the distance between two points on a straight line, it is more challenging for them when they have to find the distance between two points along a curve. This article, by the way of an example problem will show how
The inverse of a matrix exists only if the matrix is non-singular, that is, if the determinant is not 0. We can simply find the inverse of a square matrix using the determinant and adjoint using the formula belowif det(A) != 0 A-1 = adj(A)/det(A) else "Inverse does not exist...
A square matrix for which you want to compute the inverse must be a square one. It means the matrix should have an equal number of rows and columns. The determinant for the matrix should not be zero. If it is zero, you can find the inverse of the matrix. The theoretical formula for...
