Inner matrix dimensions must agreemeans that theinnerdimensions of the matrices must match. If the first matrix has dimensions 2x9, then the second would need to be9x(something). that's just basic liner algebra/matrix multiplication. In that case, you'll need to figure out what the second ...
Using 테마복사 alpha*inv(X'X) gives the correct results but (a) Matlab suggest not doing so (although the backward slash gives the wrong results) and (b) I've always avoided multiplying by the inverse of a matrix due to potential inaccuracy. Is there a better way? Thank you...
Open in MATLAB Online Do you mean you just want to do standard matrix multipication? C = A * B Or did I misunderstand? 1 Comment Iman Askarion 18 Feb 2021 Oh well. Thinking about it more I this it is. Sign in to comment.
