WebFit a curve to the data using a single-term exponential. fitresult = fit (x,y, 'exp1' ); Compute 95% observation and functional prediction intervals, both simultaneous and nonsimultaneous. Nonsimultaneous bounds are for individual elements of x; simultaneous bounds are for all elements of x. WebGenerate data with an exponential trend and then fit the data using a single-term exponential. Plot the fit and data. x = (0:0.2:5)'; y = 2*exp (-0.2*x) + 0.1*randn (size (x)); f = fit (x,y, 'exp1') f = General model Exp1: f (x) = a*exp (b*x) Coefficients (with 95% confidence bounds): a = 2.021 (1.89, 2.151) b = -0.1812 (-0.2104, -0.152) sharepoint online inactivity timeout https://restaurangl.com
