WebSep 28, 2024 · Answers (2) I'll guess the model you want is as below, but use the curve fitting toolbox. ft (shift,xscale,yscale,x) = sin ( (x - shift)/xscale)*yscale. Now just call fit to fit the model to your data. mdl = fit (X,Y,ft,'startpoint', [shiftguess,xscaleguess,yscaleguess]); Other toolboxes have similar capability, but not quite as easy to use as ... WebIf you fit a surface, then the fit plot shows your surface fit. Click-and-drag rotation is the default mouse mode for surface plots in the Curve Fitter app. Rotate mode in the Curve Fitter app is the same as using the Rotate 3D …

WebCompute Prediction Intervals. Compute and plot observation and functional prediction intervals for a fit to noisy data. Generate noisy data with an exponential trend. x = (0:0.2:5)'; y = 2*exp (-0.2*x) + 0.5*randn (size (x)); Fit a curve to the data using a single-term exponential. fitresult = fit (x,y, 'exp1' ); Compute 95% observation and ... WebThese syntaxes are available for surfaces, or sfit objects. plot (sfit) plots the sfit object over the range of the current axes, if any, or otherwise over the range stored in the fit. plot (sfit, [x, y], z) plots z versus x and y and plots sfit over the range of x and y.

WebJan 10, 2024 · I have a set of x and y values and I need to plot them and get an equation of the curve. I have used the curve fitting tool and the smoothing spline to get a graph of the curve but there is no way to get a simple equation from that. I am looking for a way to find a curve fit for the values that an equation can also be found for.
