plotfit 1.0 Description
Description: [coef, RSquared]=plotfit(x,y,polyorder)
A simple function that accepts x,y data pairs in in the vectors "x" and "y", fits it to a polynomial of order "polyorder", plots the data and the fit, and displays the fit coefficients and the goodness-of-fit measure R-squared in the upper left corner of the graph. Set "polyorder" = 1 for straight line, = 2 for quadratic (parabola), etc. Optionally returns the polynomial coefficients and the R-squared value. Uses Matlab's polyfit, polyval, and linspace functions.

PLOTSTATS(XDATA,YDATA) generate a nice figure for the statistical visualisation of datasets. YDATA is a cell array of vectors, each vector being a group of samples to test. XDATA is a cell array of the same size of YDATA, each element being a single number representing the abscissa of the corresponding sample group in YDATA. XDATA can be omitted. Example:
ydata = {
[ 1 2 3 4 5 6 7 8 9 ]
[ 2 3 4 5 ]
10*rand(10,1) };
