% Plots a linear fit of a dataset. Multiple data sets can be chained together in an array. | |
% Pass `true` to confidence parameter to generate a 95% confidence interval for the data. | |
% Resolution parameter will generate confidence interval with a better resolution. | |
function output = plotScatterLinearFit(ds_x, ds_y, confidence, resolution) | |
range = linspace(0, max(ds_x), resolution) | |
[output, error] = polyfit(ds_x,ds_y,1); | |
if confidence | |
[outputline, delta] = polyconf(output, range, error, 'predopt', 'curve') | |
plot(range, outputline, "-"); | |
hold on | |
plot(range,outputline+delta,"r--",range,outputline-delta,"r--"); | |
hold off | |
