    MATLAB: There is no dedicated fit function for this sort of  The MATLAB Basic Fitting UI helps to fit the data, so user can calculate model coefficients and plot the model on top of this data. The MATLAB polyfit and polyval  Matlab has two functions, polyfit and polyval, which can quickly and easily fit a set of data points with a polynomial. The equation for a polynomial line is: Here  That looks like a much better fit.

    MATLAB Workshop 15 - Linear Regression in MATLAB Objectives: Learn how to obtain the coefficients of a “straight-line” fit to data, display the resulting equation as a line on the data plot, and display the equation and goodness-of-fit statistic on the graph.

    I have my data as follows with F1, F2, F3, N1, N2 and N3. I want to do a linear fit of my data and plot that. I tried polyfit as seen in my code.

    In … Linear Fit in Matlab Programming Linear fit tries to model the relationship between two variables by fitting a linear equation to observed dataset. One variable is assumed to be an explanatory variable, and the other is assumed to be a dependent variable. mdl = LinearModel.fit(tbl) creates a linear model of a table or dataset array tbl. mdl = LinearModel.fit(X,y) creates a linear model of the responses y to a data matrix X. mdl = LinearModel.fit(___,modelspec) creates a linear model of the type specified by modelspec, using any of the previous syntaxes.
