| - | * ''InvertIndices'' inverts indices of tensors | ||
| - | * ''%%InvertIndices[type]%%'' inverts indices of specified type | ||
| - | ====Examples==== | ||
| - | ---- | ||
| - | Expand a power of a product: | ||
| - | <sxh groovy; gutter: false> | ||
| - | def t = '(a*b*c)**d'.t | ||
| - | println PowerExpand >> t | ||
| - | </sxh> | ||
| - | <sxh plain; gutter: false> | ||
| - | > a**d*b**d*c**d | ||
| - | </sxh> | ||
| - | ---- | ||
| - | Expand with respect to ''a'': | ||
| - | <sxh groovy; gutter: false> | ||
| - | def t = '(a*b*c)**d'.t | ||
| - | println PowerExpand['a'] >> t | ||
| - | </sxh> | ||
| - | <sxh plain; gutter: false> | ||
| - | > a**d*(b*c)**d | ||
| - | </sxh> | ||
| - | ---- | ||
| - | Expand a square root: | ||
| - | <sxh groovy; gutter: false> | ||
| - | def t = '(a*b)**(1/2)'.t | ||
| - | println PowerExpand >> t | ||
| - | </sxh> | ||
| - | <sxh plain; gutter: false> | ||
| - | > a**(1/2) * b**(1/2) | ||
