Inverse Of A 2x2 Matrix

The function circumcircle takes input as the coordinates of the three vertices of a triangle and compute the circum center and circum radius by using the formula in terms of the length of sides and area of triangle and plot the circumcircle.

Main purpose of this problem is drawing the orthotomic surface of a bezier surface through about arbitrary source point.

Position determines the relative position of a planar point C with respect toa planar segment joining A and B. This is not intended for 3D points.Pos=0 =>the point C is collinear with A and BPos=1=>the point C is above the segmentPos=-1=>the point C is below the segmentExampleA=[0 0 0]; B=[1 1...

The conjugate gradient method aims to solve a system of linear equations, Ax=b, where A is symmetric, without calculation of the inverse of A. It only requires a very small amount of membory, hence is particularly suitable for large scale systems.It is faster than other approach such as Gaussian...

I faced a stupid problem of getting all possible orders of variables for Cholesky decomposition of a covariance matrix. Web search offered advertisements of 60-line codes as a solution, so I decided to crack it myself. Enjoy.

Just like mean2() calculates the entire mean (a single value) of a 2D matrix, meanX calculates the entire mean for any X-dimensional matrix.Use meanX() to replace mean2() as it is much more robust (it is not just restricted to 2D matrices). Use it on a 3D, or anyD matrix, and it will work just...

X = POWERM_PADE(A,P) computes the P'th power X of the matrix A, for arbitrary real P and A with no nonpositive real eigenvalues, by the Schur-Pade algorithm. [X,NSQ,M] = POWERM_PADE(A, P) returns the number NSQ of matrix square roots computed and the degree M of the Pade approximant used.If A is...
