To find the inverse of any matrix ‘inv’ command is used. Consider two variables u and v independently. Where v is output var and u is input variable. Then command to find inverse will be v = inv ( u ). Here u^-1 is almost equal to inv(u). 1. Matlab code to find the inver...
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...
