Web5 hours ago · I am modelling some fluid flows through anisotropic material. I'd like to measure the fit of my model. In the image, the black crosses mark experimental data, the grey dotted line marks a 'best guess' model made by tweaking four different parameters. Each dot is a calculation, and they don't quite line up with the crosses in time. WebSmooth the data relative to the times in t, and plot the original data and the smoothed data. x = 1:100; A = cos (2*pi*0.05*x+2*pi*rand) + 0.5*randn (1,100); t = datetime (2024,1,1,0,0,0) + hours (0:99); B = smoothdata (A, "SamplePoints" ,t); plot (t,A) hold on plot (t,B) legend ( "Input Data", "Smoothed Data") Input Arguments collapse all
