ifilter(x,y) or ifilter(y) or ifilter([x y]) or ry=ifilter(x,y,center,width,shape,plotmode,filtermode)Keyboard-operated interactive Fourier filter function for time-series signal (x,y), with keyboard controls that allow you to adjust the filter parameters continuously while observing the effect...

suppose we have function of z(x,y). this program computes how the error in x and y will influence the error in z(x,y).error in z we defined asdelta(z)=diff(z,x)*delta(x)+diff(z,y)*delta(y), where delta(x) and delta(y) the errors in x and y measurements.diff(z,y) is the partial derivatives of z...

plot3AniAnaglyph(S,params) produces an anaglyph (red/cyan 3D) plot3 animation of the of arguments in cartesian coordinates (S = [X,Y,Z]).The animation includes the evolution and rotation of the arguments confined to a 1x1x1 cube centered at (0,0,0).

PP = PCHIPD(X,Y,D) provides the piecewise cubic polynomial which interpolates values Y and derivatives D at the sites X. This is meant to augment the built-in Matlab function PCHIP, which does not allow the user to specify derivatives.X must be a vector.If Y and D are vectors, then Y(i) and D(i)...

Converts a regular mesh defined by X,Y and Z into a regular triangulation. The output is patch data (triangles) in the faces d-deDUFd-deDt and vertices d-deDUVd-deDt format. The quadrilateral mesh faces are converted to triangles by splitting the faces into triangles according to the setting...

[a,b,c] = InverseKinematicsAM(x,y,z)This function finds the joint configurations for the waist, shoulder and elbow of the RA-01 robotic arm made by Images SI, Inc. It takes in three inputs which are the specifications of the x, y and z positions of the centre of the gripper of the robotic arm....

This function computes the (x,y) locations where two curves intersect. The curves can be broken with NaNs or have vertical segments. It is also very fast (at least on data that represents what I think is a typical application).

Tristan UrsellSub-pixel Resolved 2D ConvolutionMarch 2012 matout=matoverlay(mat1,mat2,x,y); This function takes an input matrix mat1 and creates an image of thematrix mat2 at the position (x,y) in mat1. If (x,y) are floats, then theimage is a sub-pixel bilinear representatoin of mat2 at position...

Mutual information I(X,Y) measures the degree of dependence (in terms of probability theory) between two random variables X and Y. Is is non-negative and equal to zero when X and Y are mutually independent. Conditional mutual information I(X,Y|Z) is the expected value of I(X,Y) given the value of...

Conversion routines to take a surface (a function z of (x,y) or (theta,r)) and convert this into a solid; much as meshz does, but a little more useful for outputting as an STL for frabrication in a 3D printer. There are two cases, one in Cartesian co-ordinates, and the other in polar...

POLYFIT3(X,Y,N,NUL,W) finds the coefficients of a polynomial P(X) of degree N that fits the data, P(X(I))~=Y(I), in a least-squares sense. Any of the coefficients can be forced to be zero, and data can be weighted.NUL is a vector with coefficients forced to be zero in usual order.W is a vector...

With the default settings, BINNED_PLOT(X,Y) splits vector X into bins of approximately equal size, and plots each median against the median of the corresponding Y-values, as well as their inter-quartile range. X and Y must have the same number of rows or columns.This is useful to visualize...

User inputs x,y and z values, which are the dimensions of the arrangement of core-shell spheres in x,y and z directions respectively. In the screen-shot provided, you can see a 3x3x3 arrangement of core-shell spheres. Similarly, you can give any value for x,y and z to generate your own...

Uses x,y coordinates to produce distance-based spatial weight matrices useful for spatial econometric regressions. The user is asked to input x and y coordinates, as well as a lower and upper bound threshold for the neighborhood.The code is adapted from a previous version by Shawn Bucholtz of the...

The X, Y and Z matrix arguments can be used exactly as in the surf and mesh functions. But attention to the colors, because DXF fiels do not uses RGB palete. Instead they use a scaled color palete between 0 and 255.
