sum (x dim) | Built-in Function |
Sum of elements along dimension dim. If dim is
omitted it defaults to 1 (column-wise sum).
As a special case if x is a vector and dim is omitted, return the sum of the elements. |
prod (x dim) | Built-in Function |
Product of elements along dimension dim. If dim is
omitted it defaults to 1 (column-wise products).
As a special case if x is a vector and dim is omitted, return the product of the elements. |
cumsum (x dim) | Built-in Function |
Cumulative sum of elements along dimension dim. If dim
is omitted it defaults to 1 (column-wise cumulative sums).
As a special case if x is a vector and dim is omitted, return the cumulative sum of the elements as a vector with the same orientation as x. |
cumprod (x dim) | Built-in Function |
Cumulative product of elements along dimension dim. If
dim is omitted it defaults to 1 (column-wise cumulative
products).
As a special case if x is a vector and dim is omitted, return the cumulative product of the elements as a vector with the same orientation as x. |
sumsq (x dim) | Built-in Function |
Sum of squares of elements along dimension dim. If dim
is omitted it defaults to 1 (column-wise sum of squares).
As a special case if x is a vector and dim is omitted, return the sum of squares of the elements. This function is conceptually equivalent to computing sum (x .* conj (x) dim)but it uses less memory and avoids calling conj if x is real. |
