Learn more about regress, multiple linear regression, calculations, coefficients, intervals, statistics determination Problems with Regress Function. Learn more about regression, regress 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.

Say I have 2 arrays (X and Y), each having the same size (let's say they're each 1x10). From what I understand, the regress function should help me find the relationship between X and Y (I want to draw a best fit line through the plotted data), and then give me the slope.

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.
