Changing the basis transforms the values in the array in a characteristic way that allows to define tensors as objects adhering to this transformational behavior. For example, there are invariants of tensors that must be preserved under any change of the basis, thereby ma… game maker examples https://fantaskis.com

WebEinstein introduced a convention whereby if a particular suffix (e.g., i) appears twice in a single term of an expression then it is implicitly summed. For example, in traditional notation x.y = x 1y 1+x 2y 2+x 3y 3= X3 i=1 x iy i; using summation convention we simply write x.y = x iy i. All we are doing is not bothering to write down the P !
