Multi-variable non linear regression - MATLAB Answers

WebNonlinear regression model function, specified as a function handle. modelfun must accept two input arguments, a coefficient vector and an array X —in that order—and return a vector of fitted response values. For example, to specify the hougen nonlinear regression function, use the function handle @hougen. Data Types: function_handle WebCreate two variables, x and y , from the first two columns of the count variable in the data file count.dat: load count.dat x = count (:,1); y = count (:,2); Use polyfit to compute a linear regression that predicts y from x: p = polyfit (x,y,1) p = 1.5229 -2.1911. p (1) is the slope and p (2) is the intercept of the linear predictor. inframe hydraulic tank https://mondo-lirondo.com
