Matrices Inverse Diagonal

A set of blocks for manipulating 3x3 and 4x4 matrices. In versions of Simulink prior to R12, matrices were handled in row-major form, thus the need for special blocks to handle matrices. Although Simulink can now handle arrays as signals, some users may still find the row-major approach...

rilt Regularized Inverse Laplace Transform [g,yfit,cfg] = rilt(t,y,s,g0,alpha) Array g(s) is the Inverse Laplace Transform of the array y(t), calculated by a regularized least squares method.This script is an emulation of S. Provencher CONTIN program, written in Fortran. See...

It's a simple GUI that calculates a random position of the end-effector, calculates the inverse kinematic and plot the joints' trajectory in a figure. You can send the positions to the arm's controller with the 'Send' button. For a correct execution, it must select the motors following this...

[U D] = UDFactor(P) returns matrices U and D such that U.'*D*U = P[U D] = UDFactor(P,uflag) returns matrices U and D such that U*D*U.' = Pwhen uflag is set to TRUE. Setting uflag to FALSE is equivalent torunning UDFactor with only one argument.The alogrithm of UDFactor is similar to the Cholesky...

This function takes as an input a square matrix and returns two outputs. The first is a vector containing the matrix values starting in the (1,1) entry and progressing along the anti-diagonal elements. A second output gives the sum of the elements along the anti-diagonals.For example:a = [1 2 3;...

XI = findX(X,Y,YI) estimates the XI values at which the dependentvariables Y reach or cross a specified target level YI (scalar value). If there are multiple solutions, findX finds all of them. It may be seen as the "inverse" operation of the MATLAB's functionINTERP1, under 'linear' method.X is a...
