X Y Coordinates

Both functions caculate the Lomb normalized periodogram (aka Lomb-Scargle, Gauss-Vanicek or Least-Squares spectrum) of a vector x with coordinates in t, which is essentially a generalization of the DFT for unevenly sampled data.The codes are transcriptions from Fortran of the subroutines found in...

XYZ2YBC convert form XYZ coordinate to YBC format (LRA)XYZ2YBC(X,Y,Z) convert the X,Y,Z values to Y,B,C values. assuming the bend radius is zero. the size of X,Y and Z must be the same.XYZ2YBC(X,Y,Z,R) where R is the bend radius. convert the X,Y,Z values toY,B,C values, taking in to account the...

MISO_FIRWIENER(N, X, Y) computes the optimal FIR Wiener filter of order N, given any number of (stationary) random input signals as the columns of matrix X, and one output signal in column vector Y.Requires BLOCK_LEVISON.M, also on the file exchange.By Keenan Pepper; uploaded with permission.

D = DISTMAT(X,Y) for matrices X and Y returns the distance matrix where the (i,j)th entry is the d-norm distance between the ith and jth row of X and Y respectively.DISTMAT(X,Y,d) computes a specific d-norm distance. Default=2[D,XI,YI]=DISTMAT(X,Y,d,var) gives the indices of the sorted values of...

All you have to do is to place the accelerometer in 9 different static positions and record the x, y & z values.The procedure exploits the fact that, in static conditions, the modulus of the accelerometer output vector matches that of the gravity acceleration. The calibration model incorporates...

This program digitizes plot into (x,y)-data. Using the program involves three main steps: import the graph from file, define coordinate axes and select points. After that you can save the data values into an ASCII file for later use. In order to learn more about how the program works, copy the...

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...
