MATLABFunctions for Polynomial Models Two MATLAB®functions can model your data with a polynomial. Polynomial Fit Functions Function Description polyfit polyfit(x,y,n)finds the coefficients of a polynomialp(x)of degreenthat fits theydata by minimizing the sum of the squares of the deviations of ...
But in fit([x y],z,'polyll'), z must be a column. So you can use the reshape functionhttp://nl.mathworks.com/help/matlab/ref/reshape.htmlYou can simply reshape z into a column by z=reshape(z,[],1). Of course, you should accordingly change x and y, in order that they have...
function sse = sseval(x,tdata,ydata) A = x(1); lambda = x(2); sse = sum((ydata - A*exp(-lambda*tdata)).^2); Save this objective function as a file named sseval.m on your MATLAB® path. The fminsearch solver applies to functions of one variable, x. However, the ss...
