Matlab 2d polyfitEditor's Note: This file was selected as MATLAB Central Pick of the Week. Revival of a 14 years old code (written in 1991 for MATLAB 2.x). Given a set of measured x,y pairs that a re supposed to reside on a circle, but with some added noise. A circle to these points, i.e. find xc,yc,R, such that (x-xc)^2+ (y-yc)^2=R^2.MATLAB heaviside functions using MATLAB software PART A: Plot the heaviside function using x = linspace(-1,1,1e5), and y = heaviside(x) . PART B: Use polyfit command to interpolate the data points xdp = linspace(-1,1,10) and ydp = heaviside(xdp).coefs = polyfit (x,y,2) %plot it, use polyval to calcualte function values of that fit. plot (x,y,'*',1:0.1:6,polyval (coefs,1:0.1:6),'-') So if you don't know which order matches best you can try it out and use the second return value if polyfit which is a struct. x = (0: 0.1: 2.5)'; y = erf (x);The matrices RL and RU give lower and upper bounds, respectively, on each correlation coefficient according to a 95% confidence interval by default. You can change the confidence level by specifying the value of Alpha, which defines the percent confidence, 100*(1-Alpha)%.For example, use an Alpha value equal to 0.01 to compute a 99% confidence interval, which is reflected in the bounds RL and RU.I have two matrix, A and B, each of 1000 rows and 100 columns. I need to do 100 polyfit on the columns. I can loop through the columns. But I am just wondering if there is any simple way to plug in A, B without the loop and return the result in an other matrix C.MATLAB 2D Plots. MATLAB fplot() ...

For example, directly access a column of a datetime array. For higher-dimensional arrays, expand the syntax to match the array dimensions. Consider a random 3-by-3-by-3 numeric array.To fit custom models, use a MATLAB expression, a cell array of linear model terms, an anonymous function, or create a fittype with the fittype function and use this as the fitType argument. For an example, see Fit a Custom Model Using an Anonymous Function .vq = interp1(x,v,xq) returns interpolated values of a 1-D function at specific query points using linear interpolation. Vector x contains the sample points, and v contains the corresponding values, v(x).Vector xq contains the coordinates of the query points.. If you have multiple sets of data that are sampled at the same point coordinates, then you can pass v as an array.Computer Vision .
