scatter-fit

This MATLAB function creates a scatter plot and computes the linear regression providing slope and intercept, determination coefficient and root mean squared error (RMSE).

Example 01 - The most simple call

scatter_fit(x,y);

Example 02 - Setting the same limits to x and y axes

scatter_fit(x,y,'limits',[4 16]);

Example 03 - Same limits with reference 1:1 (x==y) line

scatter_fit(x,y,'limits',[4 16],'reference',1);

Example 04 - Including color code to the scattered samples

scatter_fit(x,y,'limits',[4 16],'reference',1,'color',y);
