BT? It is the transpose of B.Khashishi said:Where did B come from?
No I never editted the equation. Do you have any ideas?Khashishi said:Err, did you edit your post? I didn't see a B in your equation before. Anyways, nevermind.
The OP had [B], which browsers treat as the start tag for bold fonts. That screwed up the equation. I edited the equation to fix that problem.Khashishi said:Err, did you edit your post? I didn't see a B in your equation before. Anyways, nevermind.
OK. Let us start at the right. First: [itex]B^{T}_{j,k}=B_{k,j} [/itex], so [itex] (B^{T}\circ C)_{j,l}=\sum _{k}B^{T}_{j,k}C_{k,l}[/itex]. Then inset A at the front in the same way: [itex]A\circ (B^{T}\circ C)_{i,l}=\sum _{j}A_{i,j}(\sum _{k}B^{T}_{j,k}C_{k,l}) [/itex].kezzstar said:I am having trouble converting [D]=[A][ B]T[C] to index notation.
Notation (index notation) is a mathematical system used to represent and manipulate quantities and equations using indices or subscripts. It is commonly used in fields such as physics and engineering.
Notation (index notation) is different from other mathematical notations because it uses indices or subscripts to represent quantities, rather than traditional symbols and operators. This makes it more compact and easier to work with when dealing with complex equations or multiple variables.
There are several advantages to using notation (index notation). It allows for easier manipulation and simplification of complex equations, improves readability and compactness of equations, and is especially useful for representing vector and tensor quantities.
One limitation of notation (index notation) is that it can be difficult to learn and understand at first, especially for those who are not familiar with it. It also may not be suitable for all types of equations, as certain types of calculations may be more easily done using other notations.
The best way to learn and improve at using notation (index notation) is to practice. Familiarize yourself with the basic rules and conventions, and then work on solving equations using this notation. Additionally, seeking guidance and resources from textbooks or online tutorials can also be helpful.
