index notation उदाहरण वाक्य
उदाहरण वाक्य
- The linear operator notation is depreciated ( with possible exception of theoretical mechanics and other domains where index notation is traditionally avoided ).
- The tensor index notation applies to any object which has entities that form multidimensional arrays not everything with indices is a tensor by default.
- Therefore many calculi of explicit substitution avoid variable names altogether by using a so-called " name-free " De Bruijn index notation.
- The abstract index notation is a way to write tensors such that the indices are no longer thought of as numerical, but rather are indeterminates.
- The notations in this article are : lowercase bold for four dimensional vectors ( except for the four-gradient ), and tensor index notation.
- The tensor index notation with its Einstein summation convention is very similar to the matrix calculus, except one writes only a single component at a time.
- The index notation used in physics makes it far more convenient for practical calculations, although it makes the overall geometric structure of the theory more opaque.
- In abstract index notation, to contract two tensors with each other, one places them side by side ( juxtaposed ) as factors of the same term.
- Indeed, the expression can be considered to not be using any coordinate system at all, if you consider the expression to be using abstract index notation.
- This should not be confused with a typographically similar convention used to distinguish between tensor index notation and the closely related but distinct basis-independent abstract index notation.
