disp

Class: NonLinearModel

Display nonlinear regression model

Syntax

disp(mdl)

Description

disp(mdl) displays the mdl nonlinear model at the command line.

Input Arguments

mdl

Nonlinear regression model, constructed by fitnlm.

Examples

expand all

Create and display a nonlinear regression model.

Load the reaction data, and specify both a model function and starting values for the iterations.

load reaction
modelfun = 'rate~(b1*x2-x3/b5)/(1+b2*x1+b3*x2+b4*x3)';
beta0 = [1 .05 .02 .1 2];

Create a model of the data.

mdl = fitnlm(reactants,rate,modelfun,beta0);

Display the model.

disp(mdl)
Nonlinear regression model:
    rate ~ (b1*x2 - x3/b5)/(1 + b2*x1 + b3*x2 + b4*x3)
