Open in MATLAB Online lsline is in the Statistics Toolbox, if you do not have that product you can use polyfit() to fit a 1st order polynomial. x = 1:10; y1 = x + randn(1,10); scatter(x,y1,25,'b','*') P = polyfit(x,y1,1); ...

lme = fitlme(tbl,formula) returns a linear mixed-effects model, specified by formula, fitted to the variables in the table or dataset array tbl. example lme = fitlme(tbl,formula,Name,Value) returns a linear mixed-effects model with additional options specified by one or more Name,Value pai...
MATLAB Online で開く Hi Fitting a polynomial in Matlab to some data (x, y) is easy using polyfit as e.g. p_RvsT = polyfit(r_vs_t(:, 1), r_vs_t(:, 2), 1); However, say that my y-data has some error assigned to it. I have searched the forum, but I can't find infor...
Errorin fitlm (line 134) model = LinearModel.fit(X,varargin{:}); Any suggestions on how to fix this and to get the model to work correcly and make predictions using leave out one validation approach would be greatly appreciated!
