b = regress (y,X) returns a vector b of coefficient estimates for a multiple linear regression of the responses in vector y on the predictors in matrix X. To compute coefficient estimates for a model with a constant term (intercept), include a column of ones in the matrix X. In MATLAB, you can find using the mldivide operator as B = X\Y. From the dataset accidents, load accident data in y and state population data in x. Find the linear regression relation between the accidents in a state and the population of a state using the \ operator. The \ operator performs a least-squares regression.

Regression models describe the relationship between a response (output) variable, and one or more predictor (input) variables. Statistics and Machine Learning Toolbox™ allows you to fit linear, generalized linear, and nonlinear regression models, including stepwise models and mixed-effects models. Response variables, specified as an n -by- d matrix. n is the number of observations in the data, and d is the number of dimensions in the response. When d = 1, mvregress treats the values in Y like n independent response values.

This MATLAB function returns a vector b of coefficient estimates for a multiple linear regression of the responses in vector y on the predictors in matrix X. From MATLAB documentation: regress is for multiple linear regression. You just want to find relation between X and Y. For that polyfit command should be enough.
The most common type of linear regression is a least-squares fit, which can fit both lines and polynomials, among other linear models. b = regress(y,X) は、行列 X 内の予測子に対するベクトル y 内の応答についての多重線形回帰の係数推定値が格納されているベクトル b を返します。 定数項 (切片) があるモデルの係数推定を計算するには、1 の列を行列 X に含めます。 [b,bint] = regress(y,X) は、係数推定値の 95% 信頼区間が格納されて MS_Regress-Matlab.
