pub struct VectorF64 { /* fields omitted */ }Methods
impl VectorF64[src]
fn new(size: usize) -> Option<VectorF64>
create a new VectorF64 with all elements set to zero
fn from_slice(slice: &[f64]) -> Option<VectorF64>
fn len(&self) -> usize
fn get(&self, i: usize) -> f64
This function returns the i-th element of a vector v. If i lies outside the allowed range of 0 to n-1 then the error handler is invoked and 0 is returned.
fn set(&mut self, i: usize, x: f64) -> &mut VectorF64
This function sets the value of the i-th element of a vector v to x. If i lies outside the allowed range of 0 to n-1 then the error handler is invoked.
fn set_all(&mut self, x: f64) -> &mut VectorF64
This function sets all the elements of the vector v to the value x.
fn set_zero(&mut self) -> &mut VectorF64
This function sets all the elements of the vector v to zero.
fn set_basis(&mut self, i: usize) -> &mut VectorF64
This function makes a basis vector by setting all the elements of the vector v to zero except for the i-th element which is set to one.
fn copy_from(&mut self, other: &VectorF64) -> Value
This function copies the elements of the other vector into the self vector. The two vectors must have the same length.
fn copy_to(&self, other: &mut VectorF64) -> Value
This function copies the elements of the self vector into the other vector. The two vectors must have the same length.
fn swap(&mut self, other: &mut VectorF64) -> Value
This function exchanges the elements of the vectors by copying. The two vectors must have the same length.
fn swap_elements(&mut self, i: usize, j: usize) -> Value
This function exchanges the i-th and j-th elements of the vector v in-place.
fn reverse(&mut self) -> Value
This function reverses the order of the elements of the vector v.
fn add(&mut self, other: &VectorF64) -> Value
This function adds the elements of the other vector to the elements of the self vector. The result a_i <- a_i + b_i is stored in self and other remains unchanged. The two vectors must have the same length.
fn sub(&mut self, other: &VectorF64) -> Value
This function subtracts the elements of the self vector from the elements of the other vector. The result a_i <- a_i - b_i is stored in self and other remains unchanged. The two vectors must have the same length.
fn mul(&mut self, other: &VectorF64) -> Value
This function multiplies the elements of the self vector a by the elements of the other vector. The result a_i <- a_i * b_i is stored in self and other remains unchanged. The two vectors must have the same length.
fn div(&mut self, other: &VectorF64) -> Value
This function divides the elements of the self vector by the elements of the other vector. The result a_i <- a_i / b_i is stored in self and other remains unchanged. The two vectors must have the same length.
fn scale(&mut self, x: f64) -> Value
This function multiplies the elements of the self vector by the constant factor x. The result a_i <- a_i is stored in self.
fn add_constant(&mut self, x: f64) -> Value
This function adds the constant value x to the elements of the self vector. The result a_i <- a_i + x is stored in self.
fn max(&self) -> f64
This function returns the maximum value in the self vector.
fn min(&self) -> f64
This function returns the minimum value in the self vector.
fn minmax(&self) -> (f64, f64)
This function returns the minimum and maximum values in the self vector, storing them in min_out and max_out.
fn max_index(&self) -> usize
This function returns the index of the maximum value in the self vector. When there are several equal maximum elements then the lowest index is returned.
fn min_index(&self) -> usize
This function returns the index of the minimum value in the self vector. When there are several equal minimum elements then the lowest index is returned.
fn minmax_index(&self) -> (usize, usize)
This function returns the indices of the minimum and maximum values in the self vector, storing them in imin and imax. When there are several equal minimum or maximum elements then the lowest indices are returned.
fn is_null(&self) -> bool
This function returns true if all the elements of the self vector are equal to 0.
fn is_pos(&self) -> bool
This function returns true if all the elements of the self vector are stricly positive.
fn is_neg(&self) -> bool
This function returns true if all the elements of the self vector are stricly negative.
fn is_non_neg(&self) -> bool
This function returns true if all the elements of the self vector are stricly non-negative.
