you have to find a matrix that converts between the two basis and then you only have to multiply

eg like wat i did
 2 years ago

Coolsector Group TitleBest ResponseYou've already chosen the best response.1
for example moving from S = { (1,2) , (3,5) } basis into the standard R2 basis the matrix is 1 3 2 5 now if you multiply this matrix with S vectors you get them in the standard R2 basis
